6042 Cheshirecat           Discovered 1990 Nov. 23 by A. Natori and T. Urata at the JCPM Yakiimo Station.
Named for a cat appearing in Lewis Carroll's famous fairy tale Alice in Wonderland . Its unique characteristic is its laughing voice that lingers after the cat fades away. Name and citation proposed by T. Urata.
