HD 35520 is a single[6] star in the northern constellation of Auriga. It has a white hue and is dimly visible to the naked eye with an apparent visual magnitude of 5.92.[2] The distance to this star is approximately 2,200 light years based on parallax.[1] The radial velocity for the star is, as yet, poorly constrained.[2]

This is an aging chemically peculiar star, or Ap star, in the giant stage of its evolution, with a stellar classifications of A1 III[3] and A1p.[4] The spectrum displays abundance anomalies of helium and silicon.[7] It has been classed as a shell star[8] and has a relatively high projected rotational velocity for its class of 80 km/s.[3] The star has expanded to 23[1] times the radius of the Sun and it is radiating 1,635[1] times the Sun's luminosity from its enlarged photosphere at an effective temperature of 7,645 K.[1]
