HD 36678 is single[8] star in the northern constellation of Auriga. This star is dimly visible to the naked eye with an apparent visual magnitude of 5.83.[3] It is located at a distance of approximately 840 light years from the Sun based on parallax.[2]

This is an aging red giant star with a stellar classification of M0III.[4] It is currently on the asymptotic giant branch of the HR diagram,[4] and has expanded to ~63[2] times the radius of the Sun. The star is radiating ~875[2] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 3,950 K.[2]

The brightness of HD 36678 is suspected of being variable. Hipparcos photometry showed maximum and minimum apparent magnitudes of 5.806 and 5.855 respectively, in the Hipparcos photometric band.[6] No period was found, the variability has not been confirmed, and the star is not formally listed as a variable star.[9]
