Pegasus (pronEng|ˈpɛɡəsəs) is a northern
constellation, named after the mythological winged horse Pegasus. It is one of the 88 modern constellations, and was also one of the 48 constellations listed by Ptolemy.
α Peg (Markab), β Peg, and γ Peg, together with α Andromedae (Alpheratz or Sirrah) form the large
asterismknown as the "Square of Pegasus". 51 Pegasi, a star in this constellation, is the first Sun-like star known to have an extrasolar planet. IK Pegasiis the nearest supernovacandidate. Spectroscopic analysis of HD 209458 b, an extrasolar planet in this constellation has provided the first evidence of atmospheric water vapor beyond the solar system.

History and mythology
Pegasus was born from the blood of
Medusawhen she was slain by Perseus.
Pegasus has an appearance resembling a grazing
horse, with a large square area as its body. [http://www.coldwater.k12.mi.us/lms/planetarium/myth/Peg.gif] Due to the presence of the 4 brightest stars in the square, i.e. the 4 horses of Pegasus, this may be part of the origin of the myth of the Mares of DiomedesFact|date=May 2007, one of The Twelve Laboursof Heracles, together with another feature in the Zodiacsign of Aquarius, namely Aquarius itself, pouring out the waters.
The star formerly known as Delta Pegasi (labeled "Sirrah" in the map), one of the 4 stars in Pegasus' square, is now considered to be part of Andromeda, (α Andromedae) and is more usually called "Alpheratz." By moving the star, the square became a triangle attached to a stick body, thus resembling a wing. As a winged horse, Pegasus features in
Greek mythologyas its namesake, Pegasus.
