585 Bilkis

Bilkis (minor planet designation: 585 Bilkis) is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered by German astronomer August Kopff in 1906 February and was given the Koran name for the Queen of Sheba. Photometric observations at the Palmer Divide Observatory in Colorado Springs, Colorado in 2006–7 were used to build a light curve for this object. The asteroid displayed a rotation period of 8.5742 ± 0.0005 hours and a brightness variation of 0.40 ± 0.02 in magnitude.[2]
