Cancer is a Latin term that means “crab” and is positioned in the Northern Sky. In the second century, Greek astronomer Ptolemy cataloged the constellation of cancer. It can be found at latitudes between +90 and -60 and ranks as the 31st biggest constellation in the sky. Canis Minor, Gemini, Hydra, Leo, LeoMinor, and Lynx are its nearby constellations. Cancer is the weakest of the 13 constellations.

Visible Between Latitudes:
Early in the spring, the northern hemisphere can see Cancer, the crab constellation. At latitudes between 90 and -60 degrees, it can be seen. It is a comparatively large constellation, taking about 506 square degrees of sky. Out of the 88 constellations in the night sky, it is the 31st largest. Gemini to the west, Lynx to the north, Leo to the east, Hydra to the south, and Canis Minor to the southwest are its neighbors. It is one of the zodiac’s thirteen constellations. This indicates that it is situated along the Sun’s yearly course through the sky.
The Greek astronomer Ptolemy first identified 48 constellations in the second century, and Cancer was one of them. Latin for “the crab” is its name. In the tale of Hercules’ twelve labors, it is thought to stand in for the crab. It was sent by Hera, the goddess, to divert Hercules’ attention from his battle with the Hydra. Hercules kicks the crab so forcefully that it is launched into the night sky amid the stars when it tries to kill him. The crab attempted to snag Hercules’ toe in a different rendition, but Hercules trampled it under his foot. This constellation was regarded by certain ancient societies as the portal via which souls arrived on Earth and were born into human bodies.
How old is the Cancer constellation?
Ptolemy initially mentioned cancer in Almagest in the second century AD with the Greek name (Karkinos). In very distant antiquity, it was associated with the fourth month Duzu, which is modern June-July, and was called the Northern Gate of Sun.
The constellation of which is Cancer a part?
Being the faintest of the zodiac’s 12 constellations, there’s a strong possibility you’ve never seen Cancer the Crab. Look between Leo the Lion’s brightest star and the two brightest stars in Gemini, the Twins (Castor and Pollux), to see Cancer (Regulus). Once you arrive, you are presented to a stunning cluster with 1,000 stars.
How to find Cancer the Crab
In the Northern Hemisphere, late winter and early spring are the finest times to view Cancer in the evening sky. Following that, it is obscured by the sun’s brightness in July and August before beginning to be visible in the early sky in September. Try locating Cancer and its Beehive star cluster during a Northern Hemisphere autumn if you’re awake before morning.
Let’s assume that you have located Regulus in Leo and Castor and Pollux in Gemini. You search between them for Cancer but don’t find much. Recall that cancer is fragile. Therefore, our suggestion is to search for it in a dark rural sky.
When to look for Cancer the Crab
The month of March is always a good time to watch cancer, and the months of April and May are also good times to see it at night. It eventually begins to fade under the blaze of the June sunset.
Every year, about 10 p.m. local time, the constellation Cancer will be due south and tallest in the sky during the first week of March. (From temperate latitudes in the Southern Hemisphere, Cancer appears due north; from the tropics, it shines high overhead.) Look for Cancer to be highest in the sky in mid-March at 9 p.m. local time since stars return to the same location in the sky about four minutes earlier each day, or half an hour earlier weekly (10 p.m. local daylight saving time). Cancer reaches its zenith during the night at 8 p.m. local time by late March or early April (9 p.m. local daylight saving time).
Cancer is unexpectedly visible in a dark rural sky on a moonless night. In fact, by using a few zodiacal stars, you can find where the Crab is in the zodiac. Castor and Pollux, the two brightest stars in the Gemini constellation, shine on one side of Cancer. On the other side is Regulus, the brightest star in the constellation Leo.
Cancer’s famous Beehive star cluster
The Beehive cluster, commonly known as M44, is one of the brightest star clusters in the universe, making up for Cancer’s mediocre star population. Praesepe is another name for the Beehive (Latin for manger).
The Beehive appears as a tiny, inconspicuous cloud in a dark sky to the untrained eye. However, when viewed with regular binoculars, this hazy nebula transforms into a brilliant metropolis of stars. One of the closest open clusters to our solar system, it is. The Beehive has a higher star density than the majority of other neighboring clusters.
The stars of the V-shaped Hyades open star cluster and those of the Beehive seem to be similar in age and proper motion. It’s possible that the two clusters split off from a single, enormous space cloud of gas and dust.
A member of the zodiac
Over the centuries, Cancer’s standing as a zodiac constellation has remained unwavering. In reality, during the summer solstice in the Northern Hemisphere, the sun shone in front of the constellation Cancer more than 2,000 years ago. But that’s not the case right now. When the summer solstice sun reaches its northernmost peak for the year on or around June 21, it will be in front of the constellation Taurus.
However, Cancer continues to seem to represent the zenith and radiance of the summer sun. Even today, we still refer to the June solstice as occurring over the Tropic of Cancer rather than the Tropic of Taurus. Despite the fact that from roughly July 21 to August 10 the sun, as seen from Earth, passes in front of the constellation Cancer,
Today, the sun doesn’t move into the constellation of Cancer until roughly a month after the summer solstice in the Northern Hemisphere.
Cancer the Crab of myth
Cancer was the crab in Greek mythology that bit the foot of the Greek hero Heracles (or the Roman Hercules). The goddess Hera, who viewed Heracles as her enemy, had the crab placed in the skies after Heracles had killed it.
Cancer was known as the Gate of Men in Chaldean and Platonic philosophy in antiquity. Souls entered the freshly born babies’ bodies through this doorway, descending from the heavens above.
On the summer solstice of the Northern Hemisphere around 2,700 years ago, the sun passed in front of the Beehive cluster. Maybe the Gate of Men was identified by this heavenly nebulosity back when this cluster was at the top of the zodiac. The sun currently aligns with the Beehive cluster every year in late July or early August.
Before light pollution became a problem, people used to refer to the Beehive as a small cloud. The Praesepe, also known as the Beehive Cluster, is a reliable warning of an approaching storm, according to the Roman author Pliny. Consequently, the Beehive cluster originally functioned as a cosmic weather station.
Even though the zodiac’s faintest constellation, Cancer’s legacy is still present. Look for the dim constellation of stars known as Cancer to emerge between Gemini and Leo on a moonless, dark night.
Constellations of the zodiac
The zodiac has 12 constellations, and Cancer the Crab is one of them. Learn about its star cluster, mythology, and how to locate it in your sky.
What is the largest star in the constellation of Cancer?
Numerous prominent stars can be found in the constellation of Cancer, despite it being very dim. To begin with, there is Beta Cancri, also referred to as Al Tarf in Arabic (“the eye or “the glance). The brightest star in Cancer, Beta Cancri, is nearly 660 times as luminous as the Sun.
This K-class orange giant star, which is a member of a binary system with a 14th magnitude star, is 290 light years from Earth. This second star is located so far from the Sunabout 65 times fartherthat their orbital period must be at least 76,000 years long!
Then there is the 180 light-years distant orange massive star known as Delta Cancr. The famed Beehive Cluster (Messier 44), the second-brightest star in the Cancer constellation, is located here as well (see below). Asellus Australis, which translates to “southern donkey colt” (or “southern ass, if you’re feeling comic! ), is another name for the animal.
Gamma Cancri, an A-type white subgiant 158 light years away from Earth, is positioned a little more north. Its Latin name, Asellus Borealis, translates to “northern ass” (you guessed it!). This star’s significance and that of Delta Cancri’s are derived from their proximity to Messier 44 and their mythological relationship.
How was the constellation of Cancer discovered?
The northern sky is where you may see the Cancer constellation. Latin for “the crab” is its name. Of the 12 constellations of the zodiac, Cancer is the faintest. Its emblem is. Ptolemy, a Greek astronomer, originally listed the constellation in his Almagest in the second century CE.
The crab that Hera sent to destroy Heracles is connected to the constellation Cancer in Greek mythology. The crab is either kicked into the sky by Heracles in some myths or is placed among the stars by Hera after being trampled by the Greek hero.
The open cluster Praesepe, often known as the Beehive Cluster (Messier 44), the open cluster Messier 67, and the interacting spiral galaxies NGC 2535 and NGC 2536 are just a few of the well-known deep sky features found in Cancer.
Who or what is Cancer?
Artemis, a goddess of the moon, hunting, and virginity, is Zeus’s daughter. She is shown as a huntress with a bow and arrow and serves as a healer for women as well as a guardian of young children. The goddess Artemis is the most Cancer-like thing there is. Cancer is the nurturer of the zodiac and is ruled by the kind moon. Some people who are born under this sign are blessed with inherited healing powers.
Why is Cancer named after the crab?
The Greek physician Hippocrates, known as the “Father of Medicine,” lived from 460 to 370 BC. He is credited with coining the term “cancer.” Hippocrates used the words carcinos and carcinoma to refer to tumors that do not cause ulcers and those that do. These words, which in Greek mean “crab,” were most likely used to describe the illness because the finger-like spreading projections from a cancer reminded people of crabs’ shells. Later, the Greek phrase was translated into cancer, the Latin word for crab, by the Roman physician Celsus (25 BC 50 AD). Another Greek physician, Galen (130200 AD), referred to tumors as oncos (Greek for swelling). Although Hippocrates and Celsus’ crab analogy is still used to characterize dangerous tumors, oncologists now go by the term Galen as part of their identity.
Whom ought a Cancer should wed?
In general, Pisces and Scorpio, who are both water signs, are the most compatible with Cancer in friendships and romantic partnerships because they intuitively “understand” the emotional language of the sign. Virgo, Taurus, and Capricorn share a similar energy for holding space.
