Asteroid 90712, Wittelsbach, was discovered October 12, 1990 by Freimut Börngen and Lutz D. Schmadel at Tautenburg, Thuringia, Germany. It has a period of 4 years, 217 days.
It was named for Wittelsbach Castle, a former castle in Oberwittelsbach near Aichach, Bavaria, Germany which was the ancestral home of the German Wittelsbach family, longtime rulers of Bavaria. It was apparently given up in 1209 and dismantled for its stone, according to the archaeological evidence, although tradition says it was destroyed after Count Otto Wittelsbach murdered King Philip of Swabia.
The meaning of asteroid Wittelsbach seems to be: over the top (Martina Erskine); self-cherishing (Janis Page); petulant, extravagant, self-indulgent.
