Rebekka (minor planet designation: 572 Rebekka) is a minor planet orbiting the Sun, which was discovered on September 19, 1905, by a German astronomer Paul Götz in Heidelberg. It was named after a young lady from Heidelberg, and may have been inspired by the asteroid's provisional designation 1905 RB.
Observations performed at the Palmer Divide Observatory in Colorado Springs, Colorado during 2007 produced a light curve with a period of 5.656 ± 0.002 hours with a brightness range of 0.40 ± 0.02 in magnitude. This agrees with the 5.65 hour period measured in 1998.[4]
