Scheat and its fainter neghbour Matar (Eta Pegasi) make a good starting point for finding the NGC 7331 Group and Stephan’s Quintet. It was the first Sun-like star, other than the Sun, found to have a planet orbiting it, this discovery was first made public in 1995.. Enif, Epsilon Pegasi (ε Peg) is an orange supergiant star located at distance of 690 light years from Earth in the constellation Pegasus.
