PEGASUS
(Abbreviation:
Peg)
One of the most distinctive of the northern constellations. It commemorates the flying horse, which the hero Bellerophon rode during an expedition to slay the fire-breathing Chimæra. The main stars of Pegasus make up a square; three of these are a, b and g. The fourth is Alpheratz, which used to be included in Pegasus as d Pegasi, but has been officially – and, frankly, illogically – transferred to Andromeda, as a Andromedæ. In Pegasus, excluding Alpheratz, there are nine stars above the fourth magnitude.
