HD 224635 and HD 224636 is a pair of stars comprising a binary star system in the constellation Andromeda. They are located approximately 94 light years away [7] and they orbit each other every 717 years. [2]
The primary star is HD 224635, a magnitude 6.46 [2] star (making it visible by the naked eye under very favourable conditions) with a spectral type F8 [4] that is 1.19 times more massive than the Sun. [8]
The secondary star is the slightly fainter HD 224636, with an apparent visual magnitude of 6.72, [2] a spectral type G1, [4] and 1.13 times more massive than the Sun. [8]
