The system is approximately 41 light years distant. A 1488 Latin translation depicts cancer as a large crayfish,[22] which also is the constellation's name in most Germanic languages. Cancer occupies an area of 506 square degrees and is the 31st largest constellation. The constellation of Cancer is invisible to the naked eye under city lights. Right Ascension: 7 h; Declination: +20 o Despite this, it is not particularly conspicuous. Xi Cancri is a spectroscopic binary star approximately 381 light years distant. 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. Asellus Borealis – γ Cancri (Gamma Cancri). Hercules crushed the crab and Hera placed it in the heavens as the constellation Cancer. Cancer constellation is located in the northern sky. It is based on data obtained through five filters. Cancer in ancient times used to be the location of the sun’s most northerly position in the sky. In Hubble photos, bright Milky Way stars will sometimes appear as pinpoints of light with prominent lens flares. Cancer (Birthday June 22 – July 22) is a Y shaped constellation located in the northern sky. Its traditional name, Tegmine, means “the shell of the crab.” The system has an apparent magnitude of 4.67. Cancer lies between the constellations Gemini and Leo. The brightest component, Alpha Cancri A, is a white A-type main sequence dwarf. It belongs to the NGC 2841 group of galaxies, along with NGC 2537, NGC 2541, and NGC 2552 in the constellation Lynx. Its astrological symbol is (Unicode ♋). In Ancient Rome, Manilius and Ovid called the constellation Litoreus (shore-inhabiting). Cancer (pronounced ˈkænsər) is the Latin name of a large constellation (in fact it extends itself for about 33 degrees across the sky) situated close to the celestial equator.As such, it is at least partly visible from both hemispheres in certain times of the year. 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. The Beehive Cluster is an open star cluster about 577 light years from Earth. Delta and Gamma Cancri, the northern and southern donkey, are usually associated with an old Greek myth. 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. Greek astronomer Ptolemy catalogued cancer constellation in the 2nd century. This pair is at its greatest separation around 2019.[1]. NGC 2608 is a barred spiral galaxy, 62,000 light years across, with an apparent magnitude of 13.01. 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. Gemini is a northern constellation which is located between the Cancer and Taurus constellations. 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. The brightest stars in the cluster are blue-white in colour and with magnitudes ranging between 6 and 6.5. 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). The cluster was discovered by the German astronomer Johann Gottfried Koehler in 1779. Constellation Cancer the Crab, is an ecliptic constellation laying between constellation Gemini and constellation Leo. It lies in the second quadrant of the northern hemisphere. 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. The constellation lies between Gemini, the twins and Leo, the lion. Cancer contains two Messier objects – the Beehive Cluster (M44, NGC 2632) and M67 (NGC 2682) – and has two stars with known planets.
