Notes36 Persei is an old and solitary star that has consumed its hydrogen reserves and is in the process of expanding into its giant phase. It is currently more than twice the diameter of the Sun, and is projected to expand further as its stellar evolution continues.

36 Persei is somewhat hotter and somewhat larger than Earth's own Sun. It lies more than one hundred and twenty light years distant, in the constellation of Perseus.
