Alhena B is a yellow dwarf star similar in many ways to the Sun. It orbits the main white subgiant Alhena A following a highly eccentric path taking nearly thirteen years to complete. Alhena A is seen here in the distance, though in fact the white star is the larger and more luminous of the binary pair.
