HD 90156

HD 90156 is a 7th magnitude G-type main sequence star located approximately 73 light years away in the constellation Hydra. This star is smaller, cooler, fainter, and less massive than our Sun. Also its metal content is over half as much as the Sun. In 2009, a gas giant planet was found in orbit around the star.
This star was designated as Gamma Antliae by Lacaille, and Gould intended to keep it in that constellation. However, the delineating of constellation boundaries in 1930 saw it transferred to Hydra.
