HD 82943
HD 82943 (164 G. Hydrae) is a yellow dwarf star approximately 89 light-years away in the constellation of Hydra. Two extrasolar planets have been confirmed to be orbiting it, and it is thought that the system had more giant planets that were "swallowed" by the parent star. HD 82943 is estimated at roughly 1.15 times the mass of the Sun.

HD 168746 b is an extrasolar planet orbiting the star HD 168746. It has a minimum mass about one fourth that of Jupiter, so it is most likely a gas giant. It orbits very near the star in a so-called "torch orbit" completing one revolution in only about six and half days.
