HD 20367 is a star in the constellation of Aries, close to the border with the Perseus constellation. It is a yellow-white hued star that is a challenge to view with the naked eye, having an apparent visual magnitude of 6.40.[2] Based upon parallax measurements, it is located 85 light years from the Sun. It is drifting further away with a radial velocity of +6.5 km/s.[1] Based upon its movement through space, it is a candidate member of the Ursa Major Moving Group of co-moving stars that probably share a common origin.[8]

This object is a late F-type main-sequence star with a stellar classification of F8V.[2] It is about three[6] billion years old and is spinning with a projected rotational velocity of 5.5 km/s.[6] The star is 12%[5] larger and 13%[4] more massive than the Sun. It is radiating 1.58[5] times the luminosity of the Sun from its photosphere at an effective temperature of 6,100 K.[5]
