15 Leonis Minoris

15 Leonis Minoris is the Flamsteed designation for a single star in the northern constellation of Ursa Major. It has an apparent visual magnitude of 5.12, making it a fifth magnitude star that is visible to the naked eye. The star has been examined for an infrared excess, but none was detected.

This star has a stellar classification of G0 IV-V with an age of about 9.3 billion years, which suggests that it is an older G-type main sequence star that may be evolving into a subgiant as the hydrogen at its core runs out. The disk of the star has an angular diameter of 6999810000000000000♠0.81±0.01 mas. At an estimated distance of 18.37 parsecs (59.9 light-years) based on parallax measurements, this yields a physical size of about 1.6 times the radius of the Sun. The estimated mass of the star is 15% greater than the Sun's mass. The effective temperature of the stellar atmosphere is around 5,859 K, giving it the yellow-hued glow of a G-type star.
