Discovered on 10 January 1999 by LONEOS at Anderson Mesa.
Marco Fenucci (b. 1992) is an Italian researcher at ESA's NEO Coordination Centre at the European Space Research Institute (Italy) who specializes in the dynamical characterization of asteroids. He developed a framework for the computation of proper orbital elements of planet-crossing asteroids.Naming citation (WGSBN Bull. 3, #9, 19), IAU / Minor Planet Center, via NASA/JPL
