93 Minerva (/mɨˈnɜrvə/ mi-NUR-və) is a large trinary main-belt asteroid. It is a C-type asteroid, meaning that it has a dark surface and possibly a primitive carbonaceous composition. It was discovered by J. C. Watson on August 24, 1867, and named after Minerva, the Roman equivalent of Athena, goddess of wisdom. An occultation of a star by Minerva was observed in France, Spain and the United States on November 22, 1982. An occultation diameter of ~170 km was measured from the observations.
