HD 35984 is star in the northern constellation Auriga. It has an apparent magnitude of 6.20,[2] which, according to the Bortle scale, indicates it is faintly visible to the naked eye from dark rural skies. Parallax measurements by the Hipparcos satellite indicates it lies at a distance of roughly 290 light years away.[1]
A stellar classification of F6III suggests that this is an evolved giant star that has consumed the supply of hydrogen at its core.[2] However, X-ray emission, variations in luminosity, and levels of lithium may indicate that this is instead a weak-lined T Tauri star—a low mass pre-main sequence star that is relatively poor in circumstellar matter.[7]
