HD 44219 is a solar-type star[9] with an exoplanetary companion in the equatorial constellation of Monoceros. It has an apparent visual magnitude of 7.69,[2] making it an 8th magnitude star that is too faint to be readily visible to the naked eye. The system is located at a distance of 173 light-years from the Sun based on parallax measurements, but is drifting closer with a radial velocity of −12 km/s.[1]
