36 Persei is a solitary,[8] variable star located 121 light years away from the Sun in the northern constellation of Perseus. It is visible to the naked eye as a dim, yellow-white hued point of light with a baseline apparent visual magnitude of 5.32.[2] The star is drifting closer to the Sun with a heliocentric radial velocity of −47.5 km/s,[4] and may come as close as 36.6 light-years in 661,000 years.[5]

The stellar classification of 36 Persei is F4III,[3] matching an aging giant star that has used up its core hydrogen. This object is used by astronomers as a spectral standard for stars with a similar class.[9] The star is a suspected variable of unknown type, ranging in visual magnitude from 5.29 down to 5.33,[10] and is a source of X-ray emission.[11] The star is 2.2[4] billion years old with a projected rotational velocity of 28 km/s.[6] It has an estimated 1.5[4] times the mass of the Sun and has not yet expanded significantly, having 2.3[1] times the Sun's girth. The star is radiating 8.6[1] times the luminosity of the Sun from its photosphere at an effective temperature of 6,546 [1]
