Haidea (minor planet designation: 368 Haidea) is a large asteroid residing in the asteroid belt.[1] It was discovered by Auguste Charlois on 19 May 1893 in Nice.
Its name meaning is not known; it may be taken from the opera Haydée or one of several fictional characters named Haidée. The Tagish Lake meteorite is believed to derive from 368 Haidea, due to its reflectance spectrum.[2]
