}}Patientia (minor planet designation: 451 Patientia) is the 15th-largest asteroid in the asteroid belt with a diameter of 225 km. It was discovered by French astronomer Auguste Charlois on December 4, 1899, and assigned a provisional designation 1899 EY.
It regularly reaches 11th magnitude in brightness, as in January 11, 2013, and December 12, 2017, when in favorable oppositions will be at magnitudes 10.7 and 10.4 respectively, very bright for a later-discovered minor planet.
Multiple photometric studies of this asteroid were performed between 1969 and 2003. The combined data gave an irregular light curve with a synodic period of 9.730 ± 0.004 hours and a brightness variation of 0.05–0.10 in magnitude.[9]
