631 Philippina
631 Philippina is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on March 21, 1907.
Photometric of this asteroid made in 1981 gave a light curve with a period of 5.92 ± 0.01 hours with a brightness variation of 0.20 in magnitude.[2] In 2007 lightcurve data showed that it rotates every 5.899 ± 0.001 hours.[3]
