93 Minerva is a large main belt asteroid. It is probably a C-type asteroid meaning that it has a primitive carbonaceous composition and dark surface.
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. A diameter of 171 km was measured from the observations. Since then two more occultations have been observed. [1]
