names = HIP 38558 bHD 65216 b is an
extrasolar planet located approximately 116light-year s away in theconstellation of Carina, orbiting the starHD 65216 . Thisplanet was discovered by theGeneva Extrasolar Planet Search Team in2003 . Like most planet candidates so far, it was detected with theradial velocity method.The planet has a
minimum mass about 20% more than Jupiter. Since the discovery method gives only the minimum mass, itstrue mass is probably slightly greater. The planet orbits the star in a very eccentric orbit. The mean distance from the star is slightly less than that ofMars from the Sun, but atperiastron the planet is a fifth closer to the star thanEarth from the Sun and atapoastron it is over twice as far.References
