We present physical measurements of the newly discovered asteroid, (5145) Pholus based on 7 nights of photometric observations. These observations determine an unambiguous lightcurve period of 9.9825 +/- 0.0040 hours 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.
