Scheat

Scheat, designated Beta Pegasi, is a star in the northern constellation Pegasus. It is one of the four bright stars that form the asterism known as the Great Square of Pegasus, a prominent feature in the northern sky during autumn evenings. The star is readily identifiable as an orange-hued point of light within the square and serves as a useful anchor for locating nearby constellations.

Scheat is an evolved star, currently classified as a cool giant with a spectral type around K3III.

In terms of evolution, Scheat is in a late stage of stellar life, having exhausted hydrogen in
