    • This is not a meteorite

      Many hunks of ordinary rock or metal look like meteorites. The piece of once-melted metal, called slag, is simply leftover material from an industrial furnace. Slag often contains gas bubbles, while meteorites do not. Other common "meteowrongs" include iron-rich rocks formed on Earth, fallen pieces of manmade satellites and lava rocks polished in streams.
