36 Ursae Majoris

36 Ursae Majoris is a double star in the northern circumpolar constellation of Ursa Major. With an apparent visual magnitude of 4.82, it can be seen with the naked eye in suitable dark skies. Based upon parallax measurements, this star lies at a distance of 41.7 light-years (12.8 parsecs) from Earth.

This star is a solar analog—meaning it has physical properties that make it similar to the Sun. It has 12% more mass and a radius 15% larger than the Sun, with an estimated age of 2.7 billion years. The spectrum of this star matches a stellar classification of F8 V, which indicates this is a main sequence star that is generating energy at its core through the nuclear fusion of hydrogen. The energy is being radiated into space from its outer envelope at an effective temperature of 6,126 K. This gives the star the characteristic yellow-white hue of an F-type star.

36 Ursae Majoris is thought to have a stellar companion B of spectral type K7V at wide separation (1500 AUs). An optical companion C (spectral type K2V) is located at 49,000 AUs, but is probably not bound to the system.
