Also known as Beta Pegasi, Scheat is a red giant around 200 light years from Earth, it is almost 100 times larger in diameter than our sun with twice its mass. Matar
Also known as Eta Pegasi, Matar is a binary star system around 170 light years from Earth, the primary star is a yellow giant 250 times brighter than our sun. Algenib
Also known as Gamma Pegasi, Algenib is a blue sub giant emitting 6,000 times the energy of our sun. Markab
Also known as Alpha Pegasi, Markab is a blue giant with twice the surface temperatures of the sun. Homam
