Discovered on 21 July 2001 by LONEOS at Anderson Mesa.
Jonti Horner (b. 1978) is a British-Australian astronomer at the University of Southern Queensland. He has worked on the origin and evolution of the Centaurs and Jupiter's role on impacts on Earth. Recently, he has looked at how the knowledge of our own Solar System informs studies of exoplanetary systems.Naming citation (WGSBN Bull. 3, #9, 26), IAU / Minor Planet Center, via NASA/JPL
