(11349) Witten is an asteroid of the inner main belt that was discovered on May 3, 1997 by the Belgian astronomer Eric Walter Elst at the La Silla Observatory of the European Southern Observatory in Chile ( IAU code 809). There had been several unconfirmed sightings of the asteroid: in September 1983 under the provisional designation 1983 RK at the Palomar Observatory in California and on March 21 and 22, 1993 (1993 FE 67 ) at the La Silla Observatory.
The asteroid belongs to the Vesta family , a large group of asteroids named after (4) Vesta , the second largest asteroid and third largest celestial body in the main belt. The ageless (not osculating ) orbital elements of (11349) Witten are almost identical with those of the two smaller, when one of the absolute brightness starting from 15.8 and 16.8 versus 15.0, asteroid (88622) 2001 RU 10 and ( 192195) 2007 GM 71 .
(11349) Witten was named on July 26, 2000 after the American mathematician and physicist Edward Witten .
