Vallis Schrodinger and Vallis Planck, two canyons near the moon's south pole, rival the Grand Canyon in depth and length but were formed almost instantaneously by a massive meteor impact about 3.8 billion years ago. These straight canyons, more than 1.5 miles deep and over 165 miles long, result from an impact that penetrated the lunar crust, ejecting rocks that fell back and shaped the surface in a matter of minutes. This rapid formation showcases the immense energy of the impact, significantly different from the gradual erosion that formed the Grand Canyon over millions of years.
Vallis Schrodinger and Vallis Planck, two extraordinary lunar canyons, rival the Grand Canyon in both depth and length, formed in just minutes by a massive meteor impact.
The impact that created Vallis Schrodinger and Vallis Planck threw massive rocks across the moon, forming canyons over 1.5 miles deep in less than 10 minutes.
