NotesOne of two known gas giant planets orbiting the yellow star HD 200964 in Equuleus. HD 200964 b is usually the inner of the two planets, at a distance from its star comparable with Mars' distance from the Sun. Its companion planet HD 200964 c follows an eccentric course, however, and for a brief period each orbit it actually comes closer to its star than HD 200964 b.
