11998 Fermilab           Discovered 1996 Jan. 12 by Spacewatch at Kitt Peak.
The Fermi National Accelerator Laboratory was founded in Batavia, Illinois, in 1967. Among the discoveries made by Fermilab scientists are the bottom quark and the top quark. The Sloan Digital Sky Survey also has its headquarters there. The name was suggested by P. and R. Jedicke.
