A yellow dwarf similar in size and structure to the Earth's own Sun, and some fifty light years from the Solar System. 51 Pegasi is important as possessing a planetary system.

Location of 51 Pegasi

51 Pegasi lies about halfway along the western side of the Square of Pegasus. This map shows it artificially brighter than it actually appears; in fact, to all but the keenest eyes it is too faint to be visible.
