HD 63765 is an 8th-magnitude G-type main sequence star located approximately 106 light years away in the constellation Carina. This star is smaller, cooler, dimmer, and less massive than the Sun. It has a lower iron content than our Sun, with approximately 69% of the Sun's iron-to-hydrogen ratio. In 2009, a gas giant planet was found in orbit around the star.
Planetary system
HD 63765 b is an extrasolar planet which orbits the star. This planet has at least 0.64 times the mass of Jupiter and takes 358 days to orbit the star at a semimajor axis of 0.94 AU.[2] The planet was announced in a press release dating from October 2009.
