HD 216770 b

Extrasolar planet in the constellation Piscis Austrinus

HD 216770 b is an extrasolar planet orbiting the star HD 216770. It has a mass about two thirds that of Jupiter, largest planet in the Solar System. But unlike the gas giants in the Solar System, it orbits in a very eccentric orbit around the star. The mean distance from the star is slightly larger than Mercury's, and it completes one orbit around the star in every 118 days.[1]
