A relatively faint yellow star located off the southern boundary of the Square of Pegasus, between the Square's corner stars Algenib and Markab. 70 Pegasi falls directly northward of the Circlet formation representing one of the two fish of the constellation Pisces.

Lying about 175 light years from the Solar System, 70 Pegasi is a giant star, more than ten times the diameter of the Sun. Its giant dimensions are due to the fact that it has entered the later phase of its existence, and its outer regions have swelled to form a relatively thin shell around the star. The tenuous nature of this outer shell also accounts for the fact that 70 Pegasi has a comparatively low surface temperature: some 4,800 K compared with approximately 5,800 K for the Sun.
