HD 112410 is a star in the constellation Musca. Its apparent magnitude is 6.87. It is a yellow giant of spectral type G8III located around 439 light-years distant. With around 1.54 times the mass of our Sun, it is cooling and expanding along the Red Giant Branch, having left the main sequence after exhausting its core supply of hydrogen fuel.
It has a substellar companion calculated to have a mass 9.2 times that of Jupiter and an orbital period of 124.6 days at a distance of approximately 0.57 astronomical units (AU). This is the closest planet orbiting around any ascending Red Giant Branch star, and second closest planet to a giant star after the companion of HIP 13044.
