Square of Pegasus

Square of Pegasus

The Square of Pegasus is a large, approximate square of conspicuous stars in an otherwise barren part of the northern sky. Three of the corner-stars, Markab, Scheat and Algenib, belong to the constellation Pegasus. The fourth, Sirrah, was lost to Pegasus when the constellation boundaries were formalised, and now lies just within the borders of Andromeda.
