188 Menippe is a main belt asteroid. The object has a bright surface and rocky composition. It was discovered by C. H. F. Peters on June 18, 1878, in Clinton, New York, and named after Menippe, one of the daughters of Orion in Greek mythology.

Photometric observations during 2010 showed a synodic rotation period of 11.98 ± 0.02 hours and a brightness variation of 0.28 ± 0.02 in magnitude. Because the rotation period is close to twelve hours, observations were needed at two widely separated observatories in order to build a light curve for the complete rotation.[3]
