The constellation is easily recognized by the Great Square formed by the bright stars Markab (Alpha Pegasi) at the southwest corner, Scheat (Beta Pegasi) at the northwest corner, Algenib (Gamma Pegasi) at the southeast corner, and Alpheratz in Andromeda at the northeast corner. The constellation reaches its highest point in the evening sky in October. In 1995 a planet at least half the size of Jupiter was discovered orbiting the star 51 Pegasus, which is about 40 light-years from the earth; this marked the first time a planet was detected orbiting a sunlike star outside the solar system.
Pegasus,in Greek mythology, winged horse that carries the thunderbolt of Zeus. He sprang full-grown from the neck of the dying Gorgon Medusa. With a slash of his hoof, he created the Hippocrene, a sacred spring of the Muses on Mt. Helicon. Hence, he has often been associated with the arts, especially poetry.

Pegasus(peg -ă-sŭs) An extensive conspicuous constellation in the northern hemisphere near Cygnus, with five 2nd-magnitude stars (∊, α, β, γ, and η Peg) and four of 3rd magnitude. The stars Markab (α), Scheat (β), and Algenib (γ) together with Alpha (α) Andromedae (Alpheratz) form the distinctive Great Square of Pegasus. The star 51 Pegasi, which is thought to have a planet orbiting it, is located within the Great Square. The constellation also contains the globular cluster M15 (NGC 7078), the dim spiral galaxy NGC 7331 and the group of faint galaxies known as Stephan's Quintet. Abbrev.: Peg; genitive form: Pegasi; approx. position: RA 23h, dec +20°; area: 1121 sq deg.
in ancient Greek mythology, a horse that was born from the trunk of the Gorgon Medusa when she was slain by Perseus. Pegasus was subsequently tamed by Bellerophon, who, with the horse’s help, slew the monster Chimera. A kick of Pegasus’ hoof resulted in the appearance on Mount Helicon of the spring of Hippocrene, the waters of which, according to late Attic beliefs, inspired poets. From this legend came the expression “to saddle Pegasus,” that is, to become a poet.
(sea moths, or dragonfish), the only genus of fishes of the family Pegasidae of the order Hypostomides. The fishes reach a length of 18 cm. There are five species of sea moths, distributed in the tropical coastal waters of the Indian Ocean and the western Pacific, from eastern Africa to Japan and southeastern Australia. Like poachers and pipefish, sea moths have an armor of large bony plates, which are fused on the head and body and are movable on the tail. The snout is elongated, and the mouth is small and toothless. The pectoral fins are winglike; for this reason, the Swedish naturalist C. Linnaeus named the genus after the mythical winged horse Pegasus. In Southeast Asia, dried sea moths are commercially valuable as amulets. The best-known species are P. volitans and P. natans.
