There are three major types: enstatite chondrites, carbonaceous chondrites and ordinary chondrites.
E chondrites are chondrites which are made primarily of enstatite and only account for 2% of meteorites that fall onto the Earth.
Soapstone undergoes transformations when heated to temperatures of 1000–1200 °C into enstatite and cristobalite ; in the Mohs scale, this corresponds to an increase in hardness to 5.5–6.5.
It is possible that at least some examples of enstatite chondrite meteorites originated from this asteroid, based on similar spectral analysis results.
