17518 Redqueen           Discovered 1992 Dec. 18 by A. Natori and T. Urata at the JCPM Yakiimo Station.
The Red Queen is one of the chess pieces that make up the characters in Lewis Carroll's Through the Looking Glass and what Alice found there. Alice has some very strange experiences and conversations with her.
