Hekate (minor planet designation : 100 Hekate ) is a large main-belt asteroid .
About
[ edit ]
3D convex shape model of Hekate
This is a stony S-type asteroid with a diameter of 87 +5 −4 km and a sidereal rotation period of 27.07 h .[6] It orbits in the same region of space as the Hygiea asteroid family , though it is actually an unrelated interloper. However, its geometric albedo of 0.22± 0.03[6] is too high, and it is of the wrong spectral class to be part of the dark carbonaceous Hygiea family. It is listed as a member of the Hecuba group of asteroids that orbit near the 2:1 mean-motion resonance with Jupiter .[7]
Hekate was the 100th asteroid to be discovered, by Canadian-American astronomer J. C. Watson (his fourth discovery) on July 11, 1868.[8] It is named after Hecate , the goddess of witchcraft in Greek mythology , but its name also commemorates it as the hundredth asteroid, as ἑκατόν (hekaton ) is Greek for 'hundred'.
A Hekatean occultation of a star was observed on July 14, 2003, from New Zealand .
