(398045) Vitudurum is a main belt asteroid measuring around one kilometer , which was discovered on March 19, 2009 by Markus Griesser , director of the Winterthur Eschenberg observatory , using a 40 cm telescope .
On January 12, 2017 the discoverer named the asteroid after the numbering by the Minor Planet Center with the official approval of the International Astronomical Union (IAU) after the Vicus Vitudurum from ancient Roman times and the fort built there in 294 in what is now the Winterthur district of Oberwinterthur. The name was proposed in October 2015 by the then 10-year-old student Sina Lautenschlager at the Children's University of Winterthur as part of a competition to which the discoverer invited around 300 young listeners as part of his lecture on dangerous minor planets.
