Psi

Its story

Psi Pegasi is a red giant of type M burning some 476 light-years away, on the edge of Pegasus' neck. Its deep, almost ruby colour comes from a relatively cool surface —barely three and a half thousand degrees— and from a vast radius: were it to take the Sun's place, it would swallow whole planetary orbits. It is among the warmest and most ancient embers of the winged horse's great square.
