Discovered on 20 September 1997 by L. Sarounova at Ondrejov.
The work of French poet Jean de La Ville de Mirmont (1864–1914) evoked images of unreachable horizons and bitterness. His poetic opera L'Horizon Chimérique (Fanciful Horizon) inspired the music of Gabriel Fauré. The name was suggested by R. and A. Soubie.Naming citation (WGSBN Bull. 3, #13, 8), IAU / Minor Planet Center, via NASA/JPL
