HD 156411 is a 7th magnitude G-type main sequence star located approximately 179 light years away in the constellation Ara. This star is larger, hotter, brighter, and more massive than our Sun. Also its metal content is three-fourths as much as the Sun. In 2009, a gas giant planet was found in orbit around the star.[2]
