Description

Gamma Cassiopeiae (γ Cas) is a spectroscopic binary star located in the constellation Cassiopeia. Informally known as Navi, it is one of the four brightest stars in Cassiopeia. With an apparent magnitude that varies from 1.6 to 3.0, it sometimes outshines its neighbours Schedar, Caph and Segin to become the constellation’s brightest star. Gamma Cassiopeiae lies at a distance of 550 light years from Earth. It is one of the five stars that form Cassiopeia’s recognizable W asterism.

Gamma Cassiopeiae has the stellar classification B0.5 IVe, indicating a subgiant star appearing blue or blue-white in colour. The star is running out of the supply of hydrogen in its core and is on its way to evolving into a giant. The “e” suffix indicates hydrogen emission lines in the star’s spectrum. These lines are caused by a circumstellar disk of material lost from the star.
