HD 34790

HD 34790 is a double-lined spectroscopic binary star system in the northern constellation of Auriga. It has a combined apparent magnitude of 5.66, which means it is faintly visible to the naked eye. Based upon observations by the Gaia space telescope, it is located around 317 light-years away. It has a combined stellar classification of A1Vs, matching that of an A-type main sequence star.
The two stars orbit each other with a period of only 2.15 days and an eccentricity of zero, indicating their orbit is close to circular. They are orbiting sufficiently close to each other that their rotation periods have most likely become tidally locked—meaning they always maintain the same face toward each other.
A faint third star away, shares a common proper motion and almost identical parallax. Any orbit is likely to take over a million years. The star is a faint red dwarf.
