At an ultra-high speed, estimated at roughly 78,000 mph, the meteorite could have left a sizable mark.

Furthermore, the insights gained don't have to be confined to our planet.

One of the oldest unsolved riddles in planetary science concerns the origin of the moon. Over a century ago, George Darwin proposed that tidal and centrifugal forces on a rapidly rotating proto-Earth caused the moon to be spun off into an Earth orbit.
