100 Hekate is a large Main belt asteroidAn asteroid is a small, solid object in our Solar System, orbiting the Sun. An asteroid is an example of a minor planet (or planetoid , which are much smaller than planets. The asteroids are believed to be remnants of the protoplanetary disc which were no. It is classified as a part of the Hygiea asteroid family . However, its albedoNote: This article discusses the physical or planetological property of albedo. For other usage, see Albedo (disambiguation). The albedo is a measure of reflectivity of a surface or body. It is the ratio of electromagnetic radiation reflected to the amoun of 0.19 is too high for a typical C-typeC-type asteroids are carbonaceous asteroids. They form 75% of known asteroids, and are extremely dark ( albedo 0. 03), similar to carbonaceous chondrite meteorites (types CI and CM). They dominate the outer belt beyond 2. These asteroids have approximatel asteroid, so it is likely an interloper and not a real physical member of the family.
Hekate was the 100th asteroid discovered. It was discovered by J. C. Watson on July 11, 1868 and named after Hecate, the goddess of witchcraft in Greek mythology.
Occultation of a star by Hekate was observed on July 14, 2003 from New Zealand.
