501 Urhixidur is a relatively large (ranked 372nd by IRAS) main belt asteroid. It was discovered by Dr. Maximilian Franz Joseph Cornelius Wolf (1863–1932), at the Königstuhl Observatory in Heidelberg, Germany on January 18, 1903. Like 500 Selinur and 502 Sigune, it is named after a character in Friedrich Theodor Vischer's then-bestseller satirical novel Auch Einer.[3]
Its rotational period was reported as 15 hours in 1992, but corrected to 13.174 hours in 2013.[4]
