48 Cassiopeiae is a star system in the constellation Cassiopeia. It is approximately 116.9 light years from Earth. The primary component, 48 Cassiopeiae A, is a white A-type subgiant with an apparent magnitude of +4.71. It has an astrometric companion, 48 Cassiopeiae B, which is a F-type main sequence dwarf with an apparent magnitude of +6.41. These two stars orbit around their common centre of mass once every 60.5 years. Component B has a semi-major axis of 0.62 arcseconds, or 22 AU.

  • 48 Cassiopeiae is a star system in the constellation Cassiopeia. It is approximately 116.9 light years from Earth. The primary component, 48 Cassiopeiae A, is a white A-type subgiant with an apparent magnitude of +4.71. It has an astrometric companion, 48 Cassiopeiae B, which is a F-type main sequence dwarf with an apparent magnitude of +6.41. These two stars orbit around their common centre of mass once every 60.5 years. Component B has a semi-major axis of 0.62 arcseconds, or 22 AU. A third companion, 48 Cassiopeiae C, is a fourteenth magnitude star located 24 arcseconds, or at least 850 AU, away. The primary is also a spectroscopic binary, and has an unresolved companion, meaning the system has at least four components.
