Minerva (minor planet designation : 93 Minerva ) 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 24 August 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 22 November 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.[5] [6]

On 16 August 2009, at 13:36 UT Keck Observatory 's adaptive optics system revealed that the asteroid 93 Minerva possesses 2 small moons.[7] [7] Aegis [8] [9] Gorgoneion [8] [10]
