252 Clementina is a large main belt asteroid that was discovered by French astronomer Henri Joseph Anastase Perrotin on 11 October 1885 in Nice, France.[3] The origin of the name is not known.

Photometric observations of this asteroid at the Organ Mesa Observatory in Las Cruces, New Mexico, during 2012 gave a light curve with a period of 10.864 ± 0.001 hours and a brightness variation of 0.37 ± 0.02 in magnitude. This result is in agreement with previous studies.[2]
