36 Arietis is a star in the northern constellation of Aries. 36 Arietis is the Flamsteed designation. It is a dim, orange-hued star that is a challenge to view with the naked eye, having an apparent visual magnitude of 6.40. Based upon an annual parallax shift of 8.59±0.04 mas, this star is located 380 light-years (120 parsecs) away from the Sun. It is moving closer to the Earth with a heliocentric radial velocity of −34 km/s, and is a member of the Wolf 630 moving group of stars that share a common motion through space.

This object is an evolved giant star with a stellar classification of K2 III. It is around two million years old with a similar mass as the Sun. With the hydrogen at its core exhausted, the star has expanded to ten times the girth of the Sun. It has a higher than solar metallicity, showing a high abundance of iron in its spectrum. The star is radiating 44 times the Sun's luminosity from its enlarged photosphere at an effective temperature of 4,749 K.
