Cancer constellation – Let’s Expand Our Knowledge About It

Cancer is known to have two other constellations as neighbouring astrological zodiac signs. On its right side is Leo, the Lion, and on its left side are the Twins, Gemini. Cancer lies on the ecliptic plane as all the other Zodiac constellations do. The path the sun takes as it travels across the sky in a year is called an annual path. Cancer is one of the four cardinal signs, the Cancer zodiac being one of them. When the sun crosses through the cardinal signs of the seasons, it is the start of a new season. A rise in Cancer is a sign that the summer season is approaching.

Cancer, along with the signs Aries, Taurus, Gemini, and Leo, can be found in the eastern celestial hemisphere.


Cancer Star Sign Meaning

The Cancer Star Constellation is found in the northern part of the sky. In Latin, it is known as “crab.” The 12 zodiac constellations include Cancer, the weakest of them all. The feminine symbol is ♋. The Greek astronomer Ptolemy catalogued the constellation in his Almagest, which was completed in the 2nd century CE.

Cancer, the crab sent by Hera to defeat Heracles, is found in the stars of the constellation. The crab was either booted into the sky by Heracles or thrown into the sky by Heracles, according to different versions of the narrative. (also known as Hercules) or placed among the stars by Hera (who is known as Juno in Roman mythology) after Heracles crushed it. Some of the famous deep-sky objects found in Cancer are Messier 44, the Beehive Cluster (also known as Messier 44), Messier 67, and NGC 2535, and NGC 2536, which are all open clusters.


Cancer Star Constellation – Basic Fact And Location

Cancer is the 31st biggest constellation in the sky, with a 506 square degree size. It is located in the northern hemisphere (or hemispherical region) in the second quadrant (NQ2) and is visible at longitudes ranging from 90° to -60°. In addition to those eight constellations listed above, the nearby star clusters include Canis Minor, Gemini, Hydra, Leo, Leo Minor, and Lynx.

The Cancer star constellation contains two Messier objects –(1) the Beehive Cluster and (2) M44. Al Tarf, known as Beta Cancri, is the brightest star in the constellation. Delta Cancri is the only meteor shower in the constellation; the others are attributed to different constellations.

Many known stars make up the constellation of Cancer. A list of stars that have been approved by the International Astronomical Union (IAU) can be found here: 1. Acubens, 2. Asellus Australis, 3. Asellus Borealis, 4. Copernicus, 5. Gakyid, 6. Meleph, 7. Nahn, 8.Piautos, 9.Tarf, and 10.Tegmine


Cancer Constellation Myth

The myth of Heracles’ Twelve Labours has Cancer symbolised as the crab (represented by the Hercules constellation). While fighting the Lernaean Hydra, the serpent-like beast with many heads and poisonous breath, known as Hydra, Hera sends the crab to distract Hercules. Heracles then succeeds in hurling the crab to the heavens.

Another version has Hera crushing the crab in anger, and then she places it in the sky as a show of gratitude for the help the crab had provided. Nevertheless, she places the crab in a sky that is void of bright stars, because even though the crab worked hard, it was unsuccessful in its goal. No fifth-magnitude or brighter stars have been discovered in cancer.


Cancer constellation: Major Stars

1. Acubens - Alpha Cancri

Only the fourth brightest star in Cancer, Alpha Cancri, is also known as Acubens. This star appears to vary between magnitude 4.2 and 4.3. Alpha Cancri is a system of two stars, Alpha Cancri A and Alpha Cancri B, that are located approximately 174 light-years from Earth. White A-type main sequence dwarf, Alpha Cancri A is the brightest component. A companion ten times fainter than the main star, Alpha Cancri B, is present. It is suspected that the brighter star in the system is a binary system that consists of two stars that are separated by 0.1 arc seconds.

2. AI –Tarf – Beta Cancri

The Beta Cancri star has an apparent magnitude of 3.5 and is the brightest in the constellation. It is a binary star, where the orange K-type giant is accompanied by a fourteenth magnitude companion that is 29 arc seconds away. It is estimated that Beta Cancri is approximately 290 light-years away. Beta Cancri’s traditional name is AI Tarf.

3. Asellus Australis - Delta Cancri

Delta Cancri has an apparent magnitude of 3.94, making it an orange giant. It is at a distance of 180 light-years. This star is one of the two brightest stars in the constellation of Cancer. Arkushanangarushashutu is the longest known star name. The southeastern star in the Crab constellation is called Hammurabi’s stele in ancient Babylonian. Although these species have several other common names, the one used by scientists is Asellus Australis, which means “southern donkey colt” in Latin.

4. Asellus Borealis - Gamma Cancri

Gamma Cancri is a subgiant with an A-type stellar classification (an evolved or older subgiant star), which is approximately 158 light-years distant. An apparent magnitude of 4.66 has been calculated for it. Although commonly known as “Donkey,” the traditional name of the star, Asellus Borealis, actually means “Northerly Donkey Colt.” Gamma Cancri is located near the ecliptic, just like Alpha and Delta Cancri.

5. 55 Cancri

55 Cancri consists of a yellow dwarf star (G8V spectral class) and a red dwarf (whose spectral type is not visible to the naked eye). Approximately 41 light-years away, the system is located.

6. Tegmine - Zeta Cancri

Zeta Cancri is a system of approximately 83.4 light-years from Earth that contains multiple stars. No fewer than four stars are in it. It is known as Tegmine, which translates to “the shell of the crab.” There is an apparent magnitude of 4.67 for the system.

7. Lambda Cancri

A blue-white B-type main sequence dwarf star that is approximately 419 light-years distant is known as Lambda Cancri. The apparent magnitude of this object is 5.92.

8. Xi Cancri

Xi Cancri is a spectroscopic binary star with an orbital period of approximately 381 years that is located in the constellation of Cancer. Some sources refer to this group as “Nahn.”


Xi Cancri A, a yellow G-type giant, has a magnitude of 5.16, and Xi Cancri B, a neighbouring star located only 0.1 arc seconds away, are both parts of the Xi Cancri system. A common assumption is that the stars have an orbital period of four years.


Summary

Cancer is the faint zodiacal constellation that is located between Leo and Gemini. Many of the worlds in our universe are part of multiple-star systems and some amazing deep-sky objects are found in these dark regions.
