Petersburg is a HED achondrite (from the asteroid Vesta) meteorite, officially classified as Eucrite-pmict, that was seen to fall in the United States in 1855. A total of 1.8 kg was recovered. Witnessed falls are rare and especially valuable to science, because the stones are collected before Earth's weather can change them.
