HD 104067 is an 8th magnitude K-type main sequence star located approximately 69 light years away[1] in the constellation Corvus. This star is smaller, cooler, dimmer, and less massive than our Sun. Also its metal content is seven-eighths as much as the Sun. In 2009, a gas giant planet was found in orbit around the star.
Planetary system
HD 104067 b is an extrasolar planet which orbits the star. This planet has at least 0.16 times the mass of Jupiter and takes 55.8 days to orbit the star at a semimajor axis of 0.26 AU.[2]
