Discovered on 15 September 1998 by ODAS at Caussols.
André Baranne (1931–2021) was a French astronomer who founded the Optical Laboratory of the Marseille Observatory. He was the father of modern radial-velocity spectrographs, which allowed the detection of the first exoplanet by Michel Mayor and Didier Queloz in 1995 at the Haute-Provence Observatory.Naming citation (WGSBN Bull. 2, #15, 13), IAU / Minor Planet Center, via NASA/JPL
