70 Pegasi
What is 70 Pegasi
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.
Where it is and when to see it
70 Pegasi lies in the northern celestial hemisphere. It is visible to the naked eye under a dark sky. Its best month of the year is September: the Sun sits at the opposite point of the sky and the star culminates around midnight. How high it climbs above the horizon depends on the latitude you watch from.

The signature wall
Stelvia's sky works like a signature wall: anyone can leave their name and a message on a real star, and that signature goes up on the map for everyone to read. Signing is free.
A signature without a lock can be replaced by someone else's. The lock makes the signature permanent and lets you choose a symbolic name for the star, always shown next to the star's catalogue identifier. How the lock works

A public signature from a real person. The chosen name is a symbolic denomination within Stelvia, with no official standing or IAU recognition: the sky is not for sale and belongs to no one.
