Its story

70 Pegasi is a G8 giant that has stabilised on helium fusion in its core and expanded to nine times the Sun's size, carrying two and a half solar masses. It is also a spectroscopic binary: a fainter companion, probably a low-mass main-sequence star, traces a steeply eccentric orbit every 2.58 years. The pair drifts toward the Sun at 17 km per second from 175 light-years away.
