 Mythology of Pegasus

 This large constellation north of Aquarius and Pisces adjoins Andromeda. It represents the upper body of the winged horse that, in Greek mythology, sprang from the body of Medusa when she was beheaded by Perseus. The most distinctive feature in Pegasus is the Great Square formed by Alpha, Beta, and Gamma Pegasi, and Alpha Andromedae. The area inside the square is relatively barren, containing no stars brighter than 4th magnitude.

 A variable red giant that forms one corner of the Great Square. It varies unpredictably from magnitude 2.3 to 2.7.

Epsilon Pegasi (Enif)

 A wide double star, which consists of a yellow supergiant of magnitude 2.4 and an 8th-magnitude partner that can be seen with a small telescope or even good binoculars. This star represents Pegasus's Muzzle; its popular name is derived from the Arabic word for "nose."


 A globular cluster clearly visible with binoculars or a small telescope and about one-third the apparent width of the full Moon. It lies about 30,000 light-years away.
