648 Pippa is a minor planet orbiting the Sun. Photometric measurements made from the Oakley Southern Sky Observatory during 2012 gave a light curve with a period of 9.263 ± 0.001 hours and a variation in brightness of 0.31 ± 0.03 in magnitude. This is inconsistent with a period estimate of 5.2 ± 0.3 made in 2004.[2]
