This constellation is visible in the latitude of +90° and -60°. The star has an eleventh magnitude companion, Alpha Cancri B. Cancer Borders the bright constellations of Leo and Gemini and Canis Minor, Under city skies, Cancer is invisible to the naked eye. It lies in the second quadrant of the northern hemisphere. This can be found near the center of the constellation. In the myth, Hera sends the crab to distract Hercules while the hero is fighting the Lernaean Hydra, the serpent-like beast with many heads and poisonous breath, represented by Hydra constellation. YBP 1194 is a sunlike star in the open cluster M67 that has been found to have three planets. Beta Cancri is approximately 290 light years distant. It is 180 light years distant. Cancer (The Crab) Constellation. Gemini spreads out for over 514 square degrees. Its name is Latin for crab and it is commonly represented as one. Just to the left of Cancer is another bright constellation, Leo the Lion. This pair is at its greatest separation around 2019.[1]. They are separated by 1 arc second in the sky. Brightness: Rather faint stars. M 44 contains about 50 stars, the brightest of which are of the sixth magnitude. [11] Located 131±1 light-years from Earth,[9] it is an orange-hued giant star that has swollen and cooled off the main sequence to become an orange giant with a radius 11 times and luminosity 53 times that of the Sun. It marks the location of Praesepe (Messier 44), the famous open cluster, also known as the Beehive Cluster. It looks more like a faint, upside-down Y. The cluster was discovered by the German astronomer Johann Gottfried Koehler in 1779. Cancer is a moderately sized constellation visible in the northern sky around February, and one of the twelve members of the zodiac. Cancer is a northern constellation that can be seen by observers located between latitudes of +90 and -60 degrees. Right Ascension: 7 h; Declination: +20 o Cancer is a medium-size constellation with an area of 506 square degrees and its stars are rather faint, its brightest star Beta Cancri having an apparent magnitude of 3.5. It has an apparent magnitude of 11.03. Looking deep into the Universe, the NASA/ESA Hubble Space Telescope catches a passing glimpse of the numerous arm-like structures that sweep around this barred spiral galaxy, known as NGC 2608. Cancer is the 31st largest constellation in the sky, occupying an area of 506 square degrees. Despite having different distances when measured by the HIPPARCOS satellite, the two stars share a common proper motion and appear to be a natural binary system. In mythology, Cancer is associated with the crab in the story of the Twelve Labours of Heracles (represented by the Hercules constellation). Eratosthenes extended this as Καρκινος, Ονοι, και Φατνη (Karkinos, Onoi, kai Fatne): the Crab, Asses, and Crib. Objects of magnitude 6.5 are among the faintest visible to the unaided eye in suburban-rural transition night skies. The Cancer constellation contains six named fixed stars. Its name means “the crab” in Latin. Location. Let's say you're looking for a specific constellation in the sky, but can't find it? Messier 67, image: Sloan Digital Sky Survey. [23], The Indian language Sanskrit shares a common ancestor with Greek, and the Sanskrit name of Cancer is Karka and Karkata. The image was made from separate exposures taken in the visible, ultraviolet and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Astacus and Cammarus appear in various classic writers, while it is called Nepa in Cicero's De Finibus and the works of Columella, Plautus, and Varro; all of these words signify crab, lobster, or scorpion. [1] The star also holds a record for the longest name, "Arkushanangarushashutu," derived from ancient Babylonian language, which translates to "the southeast star in the Crab." When Hercules was fighting the Lernaean Hydra as the second of his Twelve Labors, Hera sent a huge crab to assist the Hydra by snapping at Hercules’ heels. It contains two stars with known planets, including 55 Cancri, which has five: one super-earth and four gas giants, one of which is in the habitable zone and as such has expected temperatures similar to Earth. The primary is a yellow-hued G-type bright giant star of magnitude 4.0,[14] located 330 ± 20 light-years from Earth. The cluster has the designation NGC 2632 in the New General Catalogue. In Figure 5, you can see that this extended line passes very close to Regulus. The Celestial Equator is the projection of the terrestrial equator into space. Praesepe is also one of the larger open clusters visible; it has an area of 1.5 square degrees, or three times the size of the full Moon. Links to posts … Cancer is a medium-sized constellation that is bordered by Gemini to the west, Lynx to the north, Leo Minor to the northeast, Leo to the east, Hydra to the south, and Canis Minor to the southwest. The brightest star in the constellation is Al Tarf, Beta Cancri. at the winter solstice in very remote antiquity; but afterwards it was associated with the fourth month Duzu, our June–July, and was known as the Northern Gate of Sun[...]"[19]. In another version, the crab gets crushed instead and Hera, a sworn enemy of Hercules, places it in the sky for its efforts. Cancer is best known among stargazers as the home of Praesepe (Messier 44), an open cluster also called the Beehive Cluster, located right in the centre of the constellation. It is approximately 93 million light years distant. [1] The German cartographer Johann Bayer used the Greek letters Alpha through Omega to label the most prominent stars in the constellation, followed by the letter A, then lowercase b, c and d.[4] Within the constellation's borders, there are 104 stars brighter than or equal to apparent magnitude 6.5.[a][6]. The system is approximately 41 light years distant. The Cancer constellation is amongst the 48 constellations recognized by the ancient astronomer Ptolemy and eventually became one of the 88 officially accepted by the International Astronomical Union. Cancer constellation is located in the northern sky. The Greek astronomer Ptolemy observed it and called it “the nebulous mass in the breast of Cancer.” Galileo was the first to see in through a telescope in 1609, and Charles Messier added the cluster to his catalogue in 1769. The ancient Chinese interpreted the object as a ghost or demon riding in a carriage, calling it a "cloud of pollen blown from under willow catkins. Dimensions: 505 square degrees. Also known as Altarf or Tarf,[7] Beta Cancri is the brightest star in Cancer at apparent magnitude 3.5. Cancer Best seen in the early evening in March Cancer (the Crab) is a rather small constellation of 506 square degrees without any bright stars, however, the stick figure above strongly hints at a crab-like shape. Its common name means "the claw". It is based on data obtained through five filters. That could be because you're on the wrong part of the planet to see it. Its name is Latin for crab and it is commonly represented as one. Cancer (Birthday June 22 – July 22) is a Y shaped constellation located in the northern sky. Richard Allen, in Star-names and Their Meanings, lists names for the constellation as follows: In Ancient Greece, Aratus called the crab Καρκινος (Karkinos), which was followed by Hipparchus and Ptolemy. Cancer does not have any stars brighter than fourth magnitude. Because the stars in Cancer are so dim, it is best viewed via telescope, in an open area away from large cities that shine too much light. Its apparent magnitude varies between 4.20 and 4.27. Beta Cancri is the brightest star in the constellation, with an apparent magnitude of 3.5. NGC 2535 and NGC 2536 are spiral galaxies in Cancer that are interacting with each other. It is best known for its deep sky objects, and in particular the open cluster M44, the Beehive cluster or Praesepe. [2] Covering 506 square degrees or 0.921% of the sky, it ranks 31st of the 88 constellations in size. Asellus Borealis – γ Cancri (Gamma Cancri). The Beehive Cluster is also called Praesepe, which means “the manger” in Latin. Almost all the stars in the cluster are roughly at the same distance and of the same age (with the exception of 30 or so blue stragglers), which makes M67 one of the most observed and studied objects by those studying stellar evolution. The constellation lies between Gemini, the twins and Leo, the lion. The stars have an orbital period of 4.66 years. The cancer constellation is visible easily. The Ecliptic is the path that the Earth takes round the Sun. Gamma Cancri is a white A-type subgiant approximately 158 light years distant. The star’s traditional name, Asellus Borealis, means “northern donkey colt.” Like Alpha and Delta Cancri, Gamma Cancri is also located near the ecliptic and can be occulted. Cancer is a faint constellation located just east of Gemini and north of the head of the sprawling constellation Hydra. ", The smaller, denser open cluster Messier 67 can also be found in Cancer, 2600 light-years from Earth. The zodiacal constellation of Gemini is the 30 th largest constellation in the sky. In Greek mythology, the constellation Cancer is associated with the crab sent by Hera to kill Heracles. Cancer can be seen in the early spring in the northern hemisphere, and in the autumn in the southern hemisphere. (Others are our solar system, Gliese 581 in the constellation Libra and HD 10180 in Hydrus.) (In Latin, praesepe can mean both “hive” and “manger.”). Its traditional name, Tegmine, means “the shell of the crab.” The system has an apparent magnitude of 4.67. On this line the sun now falls within the constellation of Taurus at the summer solstice, but in ancient times it was in the constellation of Cancer. The planet nearest to the star is believed to be a terrestrial planet with a mass similar to Neptune, while the outermost planets are believed to be Jovian planets, with masses comparable to that of Jupiter. The name of the constellation is Latin for crab, the representative symbol. This position now occurs in Taurus due to the precession of the equinoxes, around June 21. Xi Cancri is a spectroscopic binary star approximately 381 light years distant. It was one of the first objects Galileo observed with his telescope in 1609, spotting 40 stars in the cluster. At magnitude 3.9 is Delta Cancri, also known as Asellus Australis. Located at the center of the constellation is Praesepe(Messier 44), one of the closest open clusters to Earth and a popular target for amateur astronomers. In Telugu it is "Karkatakam", in Kannada "Karkataka" or "Kataka", in Tamil Karkatan, and in Sinhala Kagthaca. The Tropic of Cancer is a line of latitude which marks the most northerly point at which the sun can be viewed directly overhead. The galaxy was discovered by William Herschel in 1783. Located in the Northern Sky, Cancer is a Latin word which means ‘crab’. Erastosthenes wrote that, in the war between the gods and the Giants that came after the clash with the Titans, the gods Hephaestus, Dionysus and several others rode on donkeys into battle. It is the 31st largest constellation in the sky and can be located at latitudes between +90° and -60°. The constellation of Cancer is a very unique constellation as it is the only constellation that represents two symbols at once. 55 Cancri is a double star that consists of a yellow main sequence dwarf belonging to the spectral class G8V and a 13th magnitude red dwarf that can only be seen through a telescope. The galaxy was discovered in the late 18th century by Friedrich Wilhelm Herschel. While rather small, Cancer still has a number of fine objects, including a … It contains two stars with known planets, including 55 Cancri, which has five: one super-earth and four gas giants, one of which is in the habitable zoneand as s… The stars represent the donkeys that the god Dionysus and his tutor Silenus rode in the war against the Titans. Cancer is a medium-size constellation with an area of 506 square degrees and its stars are rather faint, its brightest star Beta Cancri having an apparent magnitude of 3.5. It is the second brightest star in Cancer. [9], Iota Cancri is a wide double star. NGC 2608 is considered a grand design spiral galaxy. Messier 67 is an open cluster. OJ 287 is a BL Lacertae object located 3.5 billion light years away that has produced quasi-periodic optical outbursts going back approximately 120 years, as first apparent on photographic plates from 1891. The secondary is a white main sequence star of spectral type A3V and magnitude 6.57. It has an H II nucleus. The Cancer is one of the faintest constellation, and cannot be seen by naked eye most of the time. [23], Athanasius Kircher said that in Coptic Egypt it was Κλαρια (Klaria), the Bestia seu Statio Typhonis (the Power of Darkness). [1] It is most easily observed when Cancer is high in the sky. Ten star systems have been found to have planets. Zeta Cancri is a multiple star system approximately 83.4 light years from Earth. Its central supermassive black hole is among the largest known, with a mass of 18 billion solar masses,[16] more than six times the value calculated for the previous largest object. Its astrological symbol is♋. The two brightest components are a binary star with an orbital period of 1100 years; the brighter component is a yellow-hued binary pair and the dimmer component is a yellow-hued star of magnitude 6.2. [9] It spent much of its stellar life as a B-type main sequence star before expanding and cooling to its current state as it spent its core hydrogen. The Xi Cancri system consists of Xi Cancri A, a yellow G-type giant with a magnitude of 5.16, and Xi Cancri B, a companion star located only 0.1 arc seconds away. Cancer occupies an area of 506 square degrees and is the 31st largest constellation. At the (angular) heart of this sector of our celestial sphere is Praesepe (Messier 44), one of the closest open clusters to Earth and a popular target for amateur astronomers. Its stars are generally four magnitude, beta Cancri being the brightest at 3.52. It contains at least four stars. Cancer is one of these constellations and is represented by a crab. The close conjunction of Jupiter and Saturn in 1563— which was observed by Tycho Brahe and led him to note the inaccuracy of existing ephemerides and to begin his own program of astronomical measurements—occurred in Cancer not far from Praesepe. Messier 44 lies at a distance of about 577 light years from Earth. It has an area of approximately 0.5 square degrees, the size of the full Moon. It has a faint magnitude 14 red dwarf companion located 29 arcseconds away that takes 76,000 years to complete an orbit. The star is sometimes also called Al Zubanah or Sertan. Hercules crushed the crab and Hera placed it in the heavens as the constellation Cancer. The brightest component, Alpha Cancri A, is a white A-type main sequence dwarf. Cancer in ancient times used to be the location of the sun’s most northerly position in the sky. NGC 2608 is just one among an uncountable number of kindred structures. The cluster is visible to the naked eye. The Giants, who had never heard a donkey bray, thought the donkeys were monsters and fled. Cancer belongs to the zodiac family of constellations, along with Aries, Taurus, Gemini, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, and Pisces. Hercules slew the crab after it bit him in the foot. It is a medium sized constellation, 12 th constellation of Zodiac and is located on the elliptical plane, bordered by lynx to the north, Gemini to West, Leo to east and Leo minor to northeast, Canis minor to southwest and Hydra to south. It has an apparent magnitude of 6.1. Cancer lies between the constellations Gemini and Leo. The cluster is now known as Praesepe or, more popularly, the Beehive Cluster. It has an apparent magnitude of 3.7 and its estimated age is 600 million years. [24], The 41 additional constellations added in the 16th, 17th and 18th centuries. The constellation was first catalogued by the Greek astronomer Ptolemy in his Almagest in the 2nd century CE. The majority of the fainter points around NGC 2608, however, lack these features, and upon closer inspection they are revealed to be thousands of distant galaxies. The constellation can be found in the northeast section of the hemisphere near Leo and Gemini. The right ascension of cancer is nine hours, and it has a declination of 20°… The Sun is located in Cancer between July 20 and August 9, although astrologers will use other dates for their sign of the zodiac called Cancer. It is almost impossible to see Cancer as a crab with the naked eye or even binoculars. The constellation of Gemini is located in the northern hemisphere, lying in the second quadrant of the northern hemisphere (NQ2), being visible at latitudes between +90 o and -60 o.. Cancer constellation map by IAU and Sky&Telescope magazine. The Greeks and Romans identified the nebulous object as a manger from which two donkeys, represented by the neighbouring stars [1213] Asellus Borealis and [1210] Asellus Australis, were eating. Located about 590 light-years from Earth, it is one of the nearest open clusters to our Solar System. Despite this, it is not particularly conspicuous. Ptolemy described the Beehive Cluster as "the nebulous mass in the breast of Cancer." Afterwards, the goddess Hera, an enemy of Heracles, placed the crab among the stars.[20]. Showing but few stars, and its brightest stars being of only 4th magnitude, Cancer was often considered the "Dark Sign", quaintly described as black and without eyes. If you give the unique gift of naming in this area of the sky, February is the best time to locate the Cancer constellation Understanding Caring Cancer: Cancer (the Crab) is … It belongs to the NGC 2841 group of galaxies, along with NGC 2537, NGC 2541, and NGC 2552 in the constellation Lynx. The Alfonsine tables called it Carcinus, a Latinized form of the Greek word. The name Al Zubanah comes from the Arabic az-zubānah, which means “claws,” while Sertan is derived from saraţān, which means “the crab.”. Today, there are about 1010 high-probability members, most of them (68 percent) red dwarfs. Acubens belongs to the spectral class A5m and has a luminosity 23 times that of the Sun. The brightest stars in the cluster are blue-white in colour and with magnitudes ranging between 6 and 6.5. The star lies close to the ecliptic and can be occulted by the Moon and, rarely, by planets. [10] An aging star, it has expanded to around 50 times the Sun's diameter and shines with 660 times its luminosity. [21] In the 12th century, an illustrated astronomical manuscript shows it as a water beetle. In Hubble photos, bright Milky Way stars will sometimes appear as pinpoints of light with prominent lens flares. harvnb error: no target: CITEREFRidpathTirion2017 (, Centre de données astronomiques de Strasbourg, "A massive binary black-hole system in OJ 287 and a test of general relativity", "Biggest black hole in the cosmos discovered", The Deep Photographic Guide to the Constellations: Cancer, Warburg Institute Iconographic Database (over 300 medieval and early modern images of Cancer), https://en.wikipedia.org/w/index.php?title=Cancer_(constellation)&oldid=991790807, Articles containing potentially dated statements from 2002, All articles containing potentially dated statements, Creative Commons Attribution-ShareAlike License, This page was last edited on 1 December 2020, at 21:02.

Its symbol is ♋. The neighboring constellations are Canis Minor, Gemini, Hydra, Leo, Leo Minor, and Lynx. Known as Asellus Borealis "northern donkey", Gamma Cancri is a white-hued A-type subgiant of spectral type A1IV and magnitude 4.67,[12] that is 35 times as luminous as of the Sun. SN 1920A peaked at magnitude 11.7 in December 1920 and SN 2001bg was spotted in May 2001 and later peaked at magnitude 13.7. Its name is Latin for crab and it is commonly represented as one. Cancer is one of the twelve constellations of the zodiac and is located in the Northern celestial hemisphere. Praesepe, also known as Messier 44 (M44) or the Beehive Cluster, is a large, bright open star cluster located in the constellation Cancer. It is the brightest deep sky object in the constellation. Cancer is named after the Latin word for crab, and it is represented by a crab in the zodiac. In Chinese astronomy, the stars of Cancer lie within the Vermilion Bird of the South (南方朱雀, Nán Fāng Zhū Què). Its inherent water symbol and of course that of summer from the constellations positioning. The later Hindus knew it as Kulira, from the Greek Κολουρος (Kolouros), the term originated by Proclus.[23]. The Delta Cancrids are the only meteor shower associated with the constellation. [14], Located 181 ± 2 light-years from Earth,[9] Alpha Cancri (Acubens) is a multiple star with a primary component an apparent white main sequence star of spectral type A5 and magnitude 4.26. Beehive Cluster (Praesepe, Messier 44, M44, NGC 2632, Cr 189). The second pair, Zeta Cancri C and Zeta Cancri D, consists of a yellow G-type star and a 10th magnitude red dwarf separated by only 0.3 arc seconds. Cancer the Crab may be found between the two brightest stars of Gemini (Castor and Pollux) and Leo’s brightest star (Regulus). [17], Cancer was first recorded by Ptolemy in the 2nd century AD in Almagest, under the Greek name Καρκίνος (Karkinos).[18]. You can see Cancer at latitudes between +90° and -60°. Cancer lies between Leo, the lion, and Gemini, the twins. The star is also notable for its less famous name, Arkushanangarushashutu, which is the longest of all the known star names. Cancer Constellation Fixed Stars [8] Located 290 ± 30 light-years from Earth,[9] it is a binary star system, its main component an orange giant of spectral type K4III that is varies slightly from a baseline magnitude of 3.53—dipping by 0.005 magnitude over a period of 6 days. In Greek mythology, Cancer is identified with the crab that appeared while Heracles fought the many-headed Hydra. Messier 44 – the Beehive Cluster, image: Giuseppe Donatiello (CC0 1.0). Jérôme Lalande identified this with Anubis, one of the Egyptian divinities commonly associated with Sirius. Zeta Cancri is composed of two binary stars, Zeta-1 Cancri and Zeta-2 Cancri, separated by 5.06 arc seconds. This Hubble image shows a flocculent spiral galaxy called NGC 2775. This is one of the four known planetary systems known to have at least five planets. In Babylonia the constellation was known as MUL.AL.LUL, a name which can refer to both a crab and a snapping turtle. It can be seen at latitudes between +90° and -60° and is best visible during March. The proper names of stars that have been officially approved by the International Astronomical Union (IAU) are Acubens, Asellus Australis, Asellus Borealis, Copernicus, Gakyid, Meleph, Nahn, Piautos, Tarf, and Tegmine. They have an orbital period of 17 years. The Sanskrit ( Karka ) and the Greek ( Karkinos ) names for Cancer are probably derived from a common root. The red dwarf 55 Cancri B, a suspected binary, appears to be gravitationally bound to the primary star, as the two share common proper motion. The constellation of Cancer is invisible to the naked eye under city lights. As of 2002[update], the Sun appears in the constellation Cancer from July 20 to August 9. [15], Zeta Cancri or Tegmine ("the shell") is a multiple star system that contains at least four stars located 82 light-years from Earth. Richard Hinckley Allen asserted this paragraph in the late 1890s, without underlying evidence: "Cancer is said to have been the place for the Akkadian Sun of the South, perhaps from its position. Its neighboring constellations are: In tropical astrology, the Sun is considered to be in the sign Cancer from June 22 to July 22, and in sidereal astrology, from July 16 to August 16. NGC 2608 is a barred spiral galaxy, 62,000 light years across, with an apparent magnitude of 13.01. The Beehive Cluster is an open star cluster about 577 light years from Earth. Jakob Bartsch and Stanislaus Lubienitzki, in the 17th century, described it as a lobster. It is one of the oldest open clusters known. It lies in the second quadrant of the northern hemisphere (NQ2… Anyone who can see the constellation of Cancer as a crustacean, will require a bit of imagination. It is visible predominantly from November through April. Its astrological symbol is (Unicode ♋). Delta and Gamma Cancri, the northern and southern donkey, are usually associated with an old Greek myth. Leo, Canis Minor, Cancer and the Bellatrix-Betelgeuse Axis. It has an apparent magnitude of 5.92. The neighboring constellations are Canis Minor, Gemini, Hydra, Leo, Leo Minor, and Lynx. It can be seen at latitudes between +90° and -60° and is best visible at 9 p.m. during the month of March. Lee/PHANGS-HST Team/Judy Schmidt, www.geckzilla.com. It is classified as SB(s)b, which means that its spiral arms wind moderately around the prominent central bar. Two supernovae were observed in the area in recent history. 55 Cancri consists of a yellow dwarf and a smaller red dwarf, with five planets orbiting the primary star; one low-mass planet that may be either a hot, water-rich world or a carbon planet and four gas giants. The Cancer constellation gets its name from the Greek word for crab, i.e., Cancer. Cancer contains 10 named stars. Cancer is the faintest of the 12 zodiac constellations. When looking atthe constellationwith the naked eye it appears as an upside-down Y. A quadrant is essentially a quarter of a circle, which allows astronomers to measure the altitude of objects above the horizon. Its brightest star has a magnitude of only 3.5. Alpha Cancri is a multiple star system located approximately 174 light years from Earth. [11] Its common name means "southern donkey". The Cancer constellation lies in the Northern Hemisphere, between Gemini to the west and Leo to the east. Lambda Cancri is a blue-white B-type main sequence dwarf, approximately 419 light years distant. Cancer contains two Messier objects – the Beehive Cluster (M44, NGC 2632) and M67 (NGC 2682) – and has two stars with known planets. 55 Cancri A, classified as a rare "super metal-rich" star, is one of the top 100 target stars for NASA's Terrestrial Planet Finder mission, ranked 63rd on the list. Dionysus later placed the donkeys in the sky to commemorate the event. The star’s traditional name, Al Tarf (or just Tarf), is believed to be derived either from the Arabic aṭ-ṭarf, which means “the eye,” or aṭ-ṭarfah, which means “the glance (of Leo).”, Asellus Australis – δ Cancri (Delta Cancri).
