2001 Einstein is an inner main belt asteroid discovered on March 5, 1973. It is a member of the Hungaria family.[1] It is named in honour of the German-American physicist and Nobelist Albert Einstein.

Arthur C. Clarke joked in the postscript of his novel 3001: The Final Odyssey that he was hoping asteroid 2001 would be named after him, and was slightly miffed that Einstein got there first.
