ν Cassiopeiae in optical light

Nu Cassiopeiae, Latinized from ν Cassiopeiae, is a solitary[13] star in the northern constellation of Cassiopeia. With an apparent visual magnitude of +4.89,[3] it is a faint star but visible to the naked eye. Based upon an annual parallax shift of 7.92 mas as seen from Earth,[2] this star is located around 410 light years from the Sun. Cowley et al. (1969) catalogued this star with a stellar classification of B9 III,[6] indicating it has the spectrum of an evolved B-type giant star. However, Palmer et al. (1968) assigned it a class of B8 V, which would instead suggest it is an ordinary B-type main-sequence star.[7]
