HD 65216

HD 65216 is an 8th magnitude star in the constellation of Carina. It is a Sun-like yellow dwarf, 8% less massive and somewhat less luminous. It cannot be seen without technical aid, but with binoculars or telescope it should be visible.

An extrasolar planet is known to orbit the star.

HD 65216 b

The planet, designated as HD 65216 b, was discovered by the Geneva Extrasolar Planet Search Team in 2003. Like most planet candidates so far, it was detected with the radial velocity method.

The planet has a minimum mass about 20% more than Jupiter. Since the discovery method gives only the minimum mass, its true mass is probably greater, but unlikely in large amount. The plaent orbits the star in a very eccentric orbit. The mean distance from the star is slightly less than that of Mars from the Sun, but at periastron the planet is a fifth closer the star than Earth from the Sun and at apoastron it is over twice as far.
