On 2 October 1933 several stones fell with a total mass of 3.393 kg, the largest being 905 grams.

Pesyanoe is one of only 9 Aubrites (or, 'enstatite achondrites) which have been observed to fall. Aubrites were formed in an extremely reducing environment. They are characterized by their dominant phase (enstatite), but they almost always have small (tiny?) amounts of accompanying diopside, plagioclase, forsterite, Fe-Ni metal, troilite and other rare sulfides.

During the long trip from its original ancient environment to the planet earth Pesyanoe has picked up a few xenoliths. These small inclusions have minerals whose oxidized iron is foreign to Pesyanoe's dominant silicate mineralogy.
