Hypatia (stone)
Hypatia is a small stone, thought to be the first known specimen of a comet nucleus.[1][2]
Discovery
Hypatia was discovered in December 1996 by Aly A. Barakat at 25°30′E 25°20′N, in the same area where Libyan desert glass is found.[3]
Analysis
Tests done in South Africa show that Hypatia contains microscopic diamonds and that it is of extraterrestrial origin. It is thought to have been part of the body whose impact caused the creation of Libyan desert glass.[3]
