Abstract
Abstract We investigate precessing and periodic geodesic motions of timelike particles around a black-bounce/traversable wormhole. After obtaining its semi-classic and relativistic periastron advance, we find a preliminary bound on the scale length of such a spactime based on the detected precession of the star S2 around the Galactic Center. We also study periodic orbits around it and find that the variation of the scale length can change the taxonomy of the periodic orbits and cause the transition from a periodic orbit to a quasi-periodic one and vice versa.
