Lying about 190 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.
