892 Seeligeria is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on May 31, 1918 in Heidelberg and assigned a preliminary designation of 1918 DR. It was named after German astronomer Hugo Hans von Seeliger.
Photometric observations at the Oakley Observatory in Terre Haute, Indiana during 2007 were used to build a light curve for 892 Seeligeria. The asteroid displayed a rotation period of 15.78 ± 0.04 hours and a brightness variation of 0.35 ± 0.07 in magnitude.[2]
