Its story

85 Pegasi is one of the catalogue's nearest multiple systems, just 39.7 light-years away. Its primary is a yellow G5Vb dwarf very much like the Sun —0.82 solar masses and around 5600 K—, paired with a K7V orange dwarf that orbits every 26 years at 10.3 astronomical units; that secondary may itself harbour a tiny red dwarf companion. The system is some 9.3 billion years old: twice the age of our own Sun.
