Do meteorites come in different shapes?
Yes. Meteorites can be rounded, blocky, cone-shaped or broken fragments. Their shape is changed by melting and breaking as they fall.
Meteorites are not all the same shape. Their shape depends on how they broke apart and what happened as they fell through the air.
Rounded and blocky. Most meteorites are rounded lumps with smooth edges, or blocky pieces with flat sides and rounded corners. The rushing air melts their outside and smooths the sharp edges.
Cone-shaped. Some meteorites keep pointing the same way as they fall, like a shuttlecock. The front melts into a smooth cone or dome, and the back stays flatter. These are called oriented meteorites. They are rare and very special. Some even have a little ridge around the edge where melted rock flowed backwards.
Thumbprinted. Some meteorites, especially iron ones, have shallow dents all over, like thumbprints in clay. These are called regmaglypts.
Broken pieces. When a meteorite breaks apart in the air, the pieces have sharp edges that may be only partly covered in crust. If it breaks on landing, the pieces have no crust on the broken sides.
Twisted metal. Iron meteorites that explode in the air can produce jagged, twisted pieces called shrapnel, like those from the Sikhote-Alin fall in Russia in 1947.
Meteorites are never perfectly round balls, which is one way to tell them from some round Earth rocks and old cannonballs.
