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.

Photometric measurements of the asteroid made in 2004 at the Palmer Divide Observatory showed a light curve with a period of 5.487 ± 0.002 hours and a brightness variation of 0.66 ± 0.03 in magnitude.[2]
