(9500) Camelot is an asteroid of the central main belt that was discovered on September 29, 1973 by the Dutch astronomer couple Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld . The discovery was made during the 2nd Trojan survey, during which Tom Gehrels surveyed field plates recorded with the 120 cm Oschin Schmidt telescope of the Palomar observatory at the University of Leiden , 13 years after the start of the Palomar-Leiden- Surveys .

The asteroid belongs to the Eunomia family, a group named after (15) Eunomia , to which probably five percent of the asteroids in the main belt belong. The timeless (non- osculating ) orbital elements of (9500) Camelot are almost identical to those of the smaller, if one assumes the absolute brightness of 16.6 compared to 14.4, asteroids (413077) 2001 SK 321 .

(9500) Camelot was named after Camelot on November 11, 2000 , the court of King Arthur from the Arthurian legend . On the same day a few more asteroids from the 2nd Trojan survey were named after names from the Arthurian legend , for example (9499) Excalibur , (9501) Ywain , (9502) Gaimar , (9503) Agrawain and (9504) Lionel . As early as 1973, a lunar crater on the eastern front of the moon was named by astronauts on the Apollo 17 mission as a landing site after Camelot, and in 1982 a rift valley on Saturn's moon Mimas : Camelot Chasma .
