Constellation guide to the 88 official constellations which divide up the sky. These constellations are used to help navigate the celestial sphere. The Constellations are patterns in the sky which have been to invented and have deep mythology behind them. Constellations cover massive areas in the sky and as such are very easy to find.
Some of the constellations have very familiar names, such as Leo, Gemini, Virgo and Aquarius. There are 12 of these constellations and they form the Zodiac. The Zodiac constellations follow the line of the ecliptic. The ecliptic is the apparent path of the Sun on the celestial sphere.
Equleuus is the second smallest constellation, at 72 square degrees. The only constellation that is smaller is Crux.
Equuleus is associated with the foal Celaris, who was the brother of the winged horse Pegasus. Celaris was given to Castor by Mercury.
