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, but it was named for Einstein first. Asteroid 3001 was named 3001 Michelangelo.
