These are Rigel in Orion, Aldebaran in Taurus, Capella in Auriga, Castor and Pollux in Gemini, Procyon in Canis Minor, and Sirius in Canis Major constellation.

Sirius and Procyon are also part of the Winter Triangle, a smaller asterism that these two stars form with Betelgeuse in Orion.

Capella, also known as Alpha Aurigae or the Goat Star, is the brightest star in Auriga and the sixth brightest star in the sky.

The only stars in the northern celestial hemisphere brighter than Capella are Arcturus in Boötes constellation and Vega in Lyra. The only other star visible from northern latitudes that is brighter than Capella is Sirius in the southern constellation Canis Major.

Capella is sometimes called the Goat Star because its name is derived from the diminutive of the Latin capra, meaning “female goat,” and means “the little goat.”

Betelgeuse

  • by

Betelgeuse, Alpha Orionis, is the second brightest star in Orion constellation and the ninth brightest star in the sky. It is a supergiant star, distinctly red in colour, located at an approximate distance of 643 light years from Earth. It is an evolved star, one expected to explode as a supernova in a relatively near future.

Betelgeuse is a large, bright, massive star easily found in the sky in the winter months because it is part of a familiar pattern formed by the celestial Hunter. The red supergiant marks one of Orion‘s shoulders, while the hot, bright giant Bellatrix, Gamma Orionis, marks the other.
