93 Minerva (mi-nur'-va) is a large 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. Since then two more occultations have been observed, which give an estimated mean diameter of ~150 km for diameter. [1]
