Cool red star

Its story

10 Andromedae is a cool red M-type giant, one of the reddest visible to the naked eye in its constellation. Its deeply warm, reddish light crosses 481 years to reach us —it set out when Cervantes was being born in Alcalá de Henares. It belongs to the family of old, swollen stars that have already left core hydrogen burning behind and move, slowly, toward the end.
