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.[1] With around 1.54 times the mass of our Sun, it is cooling and expanding along the Red Giant Branch,[2] 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.[2]
