(471301) Robertajmolson Main-belt Asteroid
Discovered on 30 January 2006 by Spacewatch at Kitt Peak.
Art historian Roberta J. M. Olson (b. 1947) identified Halley's Comet as the model for Giotto's Star of Bethlehem in his Arena Chapel fresco in Padua. This inspired ESA to name the mission to Halley's Comet “Giotto”. Her books include Fire and Ice: A History of Comets in Art and, as a co-author, Cosmos: The Art and Science of the Universe.Naming citation (WGSBN Bull. 2, #4, 5), IAU / Minor Planet Center, via NASA/JPL
