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. 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.
