Eta Cassiopeiae is a binary system made up of a yellow G-type star (similar to Sol) with an orange K-type companion, both in the main sequence. The two stars are separated by an average distance of 71 AU, but their periapsis is 36 AU; because of this close approach, it is unlikely that there are any habitable planets in the Eta Cassiopeiae system.
