50 million years ago, this boulder rolled across the moon’s surface

The moon does n’t get a lot of activeness . Unless humans number along to muck up things up , the lunar surface remains pretty much as it has been for hundreds of million of years . But this rock managed to impart a trail in the regolith as recently as 50 million years ago . How did it manage that ?

Trails have been made on the moon at various points in lunar history , but subject field intimate that regolith buildup from micrometeorite impacts efface any evidence of movement over the track of ten of millions of years . According to current approximation , this trail , made by a bowlder nine meters in diam , would be a mere 50 - 100 million years one-time . That ’s fairly recent for movement on the Sun Myung Moon , and the common people at the Lunar Reconnaissance Orbiter advise the movement may be extralunar in origin . Perhaps the boulder was strike by a very small meteorite , pink it from its post and sending it on a rare journey through the regolith .
