Quick Facts Constellation, Right ascension ...

The primary component, ψ Cassiopeiae A, is an orange K-type giant with an apparent magnitude of +5.0;[10][11] it is a double star, designated CCDM J01259+6808AB,[12] with a fourteenth magnitude star (component B) located 3 arcseconds from the primary. Located about 25 arcseconds distant there is a 9.8 magnitude optical companion CCDM J01259+6808CD, designated ψ Cassiopeiae B in older star catalogues,[10] which is itself another double;[10][13] CD comprises a 9.4 magnitude component C and a 10 magnitude component D.[14]
