I'm going to guess a couple of factors, just judging by the pictures on twitter: * it's small but went through a lot of stuff, so it must have been going pretty damn fast * it is metal but looks scorched on the outside. It looks like other parts you'd see at a museum that have gone through through reentry. * it's too uniform of a shape to be a meteorite
