HD 32188 is suspected variable star[1] in the northern constellation of Auriga, and is positioned roughly in between Eta and Zeta Aurigae. It has a white hue and is just barely visible to the naked eye with an apparent visual magnitude that fluctuates around 6.08.[2] The distance to this star is approximately 3,000 light years, based on parallax.[3] It has an absolute magnitude of −2.87.[4]

This object is an A-type giant star with a stellar classification of A2IIIshe.[4] The suffix notation indicates this is a shell star,[5] which means it has a peculiar spectrum indicating there is a circumstellar disk of gas around the star's equator. While the spectral luminosity class is III, analysis of its colour and brightness suggest it more closely resembles a supergiant star.[4] HD 32188 has expanded to 30[3] times the radius of the Sun and it is spinning with a projected rotational velocity of 23 km/s.[6] It is radiating 2,428[3] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 7,350 K.[3]
