Courtney, Wendy and Cody have the misfortune of being the offspring of an amateur astronomer. They have managed to adjust and mature despite the often neglected paternal oversight of a sleepy dad, the first discoverer of this object.Naming citation (20010804/MPCPages.arc), IAU / Minor Planet Center, via NASA/JPL
