What is the Capricornus Constellation?

Capricorn constellation

Capricornus, often referred to as Capricorn, is a constellation in the zodiac. It is one of the 88 modern constellations and is also one of the 12 constellations in the zodiac, which means it lies along the path that the Sun, Moon, and planets travel through the sky.

The Capricornus constellation is known for its distinctive shape, which resembles a sea goat—a mythical creature with the front half of a goat and the tail of a fish. This unique shape makes it one of the more recognisable constellations in the night sky.

Stars in the Capricornus Constellation

The Capricornus constellation contains several notable stars, but it's not particularly bright compared to other constellations. Here are some of its key stars:

  • Deneb Algedi (Delta Capricorni): The brightest star in Capricornus, Deneb Algedi is a binary star system located approximately 39 light-years away from Earth. Its name means "the tail of the goat" in Arabic.
  • Nashira (Gamma Capricorni): Another significant star, Nashira is a giant star about 139 light-years from Earth. Its name translates to "the lucky one" or "the bearer of good news."
  • Dabih (Beta Capricorni): Dabih is a binary star system located about 328 light-years away. Its Arabic name means "the butcher."
  • Algedi (Alpha Capricorni): Algedi is actually a pair of double stars, Alpha¹ Capricorni and Alpha² Capricorni, located approximately 109 light-years from Earth. This pair is easily visible to the naked eye and can be resolved into two separate stars with binoculars.
  • Algiedi Prima (Alpha¹ Capricorni): Part of the Algedi system, this star is a yellow giant located about 690 light-years away. It is a binary star, though its companion star is much fainter and harder to see.
  • Algiedi Secunda (Alpha² Capricorni): The other part of the Algedi pair, this star is a yellow giant located around 109 light-years away from Earth. It is also a binary system with a fainter companion.
  • Baten Algiedi (Omega Capricorni): This star, whose name means "the belly of the goat," is a red giant located about 670 light-years away. It has a distinct reddish hue and is one of the more interesting stars to observe in the constellation.
  • Psi Capricorni: Psi Capricorni is a binary star system approximately 47 light-years from Earth. It consists of a white main-sequence star and a fainter companion star.
  • Rho Capricorni: This star is located around 146 light-years away from Earth and is known for its peculiar chemical composition, rich in elements like mercury and manganese.

While Capricornus does not have many very bright stars, its unique shape and interesting mythology make it a constellation worth exploring.

Capricornus Mythology

Capricorn Sea Goat: A Mythical Creature

The Capricorn constellation is deeply rooted in mythology. In Greek mythology, Capricornus is often associated with the god Pan. Pan, the god of the wild, shepherds, and flocks, had the legs and horns of a goat. When he was escaping from the monster Typhon, he jumped into the Nile River, and the part of his body that was submerged transformed into a fish, creating the sea goat.

Capricorn Greek God and Goddess

While Pan is the primary god associated with Capricornus, some myths also link the constellation to the goat Amalthea, who nursed the infant Zeus. In gratitude, Zeus placed her image in the sky. In astrology, Capricorn is ruled by Saturn, a god associated with time, discipline, and harvest.

Sagittarius lies to the west of Capricornus, while Aquarius is to the east. Identifying these constellations first can help you narrow down the area of the sky to search.
