HD 112410 is a star in the southern constellation of Musca. It has a yellow hue and is too dim to be readily visible to the average sight, having an apparent visual magnitude of 6.86.[2] The distance to this star is 513 light years based on parallax, and it is drifting further away from the Sun with a radial velocity of 73 km/s.[1] It has an absolute magnitude of 1.22.[2]

This is an aging giant star with a stellar classification of G8III.[3] It is cooling and expanding along the red giant branch,[5] having evolved off the main sequence after exhausting its core supply of hydrogen fuel. At present it has 10[1] times the Sun's radius. Mass estimates range from 1.21[4] up to 2.32[6] times the mass of the Sun. The star has a lower metallicity the Sun – what astronomers term the abundance of elements with more mass than helium – and it is spinning with a projected rotational velocity of 3.3 km/s.[4] It is radiating 50.5[1] times the luminosity of the Sun from its enlarged photosphere at an effective temperature of 4,793 K.[4]
