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.

Leo is a constellation of the zodiac. Leo lies between dim Cancer to the west and Virgo to the east.
This constellation contains many bright stars, such as Regulus (α Leonis), the lion's heart; Denebola (β Leonis); and Algieba (γ1 Leonis). Many other fainter stars have been named as well, such as Zosma (δ Leo), Chort (θ Leo), Al Minliar al Asad (ĸ Leo), Alterf (λ Leo), and Subra? (ο Leo).
Leo contains many bright galaxies, of which Messier 65, Messier 66, Messier 95, and Messier 96 are the most famous.
In Greek mythology, it was identified as the Nemean Lion (and may have been a source of the tale) which was killed by Hercules during one of his twelve labours, and subsequently put into the sky.
Notable Objects in Leo
Leo contains many bright galaxies; M65, M66, M95, M96, M105, and NGC 3628 are the most famous, the first two being part of the Leo Triplet.
The Leo Triplet is a small group of galaxies about 35 million light-years away.
The Leonids occur in November, peaking on November 1415, and have a radiant close to Gamma Leonis. Its parent body is Comet Tempel-Tuttle, which causes significant outbursts every 35 years.
