摘要：

We present physical measurements of the newly discovered asteroid, (5145) Pholus, based on seven nights of photometric observations. These observations determine an unambiguous lightcurve period of 9.9825 ± 0.0040 hr with a peak-to-peak amplitude of 0.15 mag. We also report a rotationally independent color of (V - R) = 0.810 ± 0.006 (Kron-Cousins R). The standard IAU two parameter fit versus solar phase angle yields HV = 7.645 ± 0.011 and GV = 0.16 ± 0.08. Except for its color and orbit, (5145) Pholus exhibits normal asteroidal properties. © 1992.
