 55 Cancri b is in a short @-@ period orbit , though not so extreme as that of the previously detected hot Jupiter 51 Pegasi b . The orbital period indicates that the planet is located close to a 1 : 3 mean motion resonance with 55 Cancri c , however investigations of the planetary parameters in a Newtonian simulation indicate that while the orbital periods are close to this ratio , the planets are not actually in the resonance .
