The Constellation Pegasus

Pegasus, a Northern constellation and the 7th largest in the sky (even though only half of the horse is depicted), is quite unique among the constellations. Within Pegasus is the star 51 Pegasi, a Sun-like star that was the first found to have a planet orbiting it. Michel Mayor and Didier Queloz announced the exoplanet’s discovery in 1995, with confirmation coming from Drs. Geoffrey Marcy and Paul Butler.
