HD 47475

HD 47475 is a G-type main-sequence star located approximately 121 light-years away in the constellation Canis Major. It is slightly larger and more luminous than the Sun. The star's apparent magnitude is around 7.7, making it too faint to be seen with the naked eye but easily observable with binoculars or a small telescope.

HD 47475 has been the subject of astrometric and radial velocity studies, leading to the discovery of an extrasolar planet, designated HD 47475 b, orbiting it.

The star's stellar parameters, such as its effective temperature, surface gravity, and metallicity, have been estimated through spectroscopic analysis. These characteristics provide insights into the star's age and evolutionary stage. The metallicity suggests that HD 47475 is slightly more metal-rich than the Sun.

The designation "HD" refers to the Henry Draper Catalogue, a comprehensive star catalog compiled in the early 20th century. This catalog provides positional and spectral information for a vast number of stars across the sky.
