253 Mathilde was discovered in 1885 by Johann Palisa. The name is thought to honor the wife of astronomer Moritz Loewy, then the vice director of the Paris Observatory.
253 Mathilde is the largest asteroid to be visited by spacecraft (NEAR in June 1997). It is 52 kilometers in diameter and is approximately four times the size of 951 Gaspra and two times the size of 243 Ida. Ida and Gaspra were visited by the Galileo spacecraft on October 29, 1991 and August 28, 1993 respectively.
Bit strange I don’t find it in the Asteroid listing of “The “Planetary Scientist’s Companion” pages 251-263. It gets a separate page 249
