A piece of the Johnstown Meteorite has again landed in Johnstown. A small part of the rock from space that fell July 6, 1924, was presented to the Johnstown Historical Society Tuesday night by its owner, Misty Lees.
The Johnstown meteorite comes from a large asteroid, probably Vesta, that melted and differentiated. It is low in iron, nickel and other elements that sank to the asteroid core. It is also poor in aluminium and calcium, which seeped to the surface in volcanic basalts like the Camel Donga meteorite in this case.
