8535 Pellesvanslös           Discovered 1993 Mar. 21 by C.-I. Lagerkvist at the European Southern Observatory.
Named for the fictional character Pelle Svanslös, a brave cat that appears in Gösta Knutsson's children's stories. Some of the adventures of this cat, whose tail was bitten off by a rat when he was only a few days old, take place in the section of Uppsala where the astronomical observatory is located.
