Moon, grand canyon and asteroid

Asteroid impact on moon blasted two grand canyons in 10 minutes
The Grand Canyon in Arizona is one of Earth's natural wonders, carved out over millions of years by the gradual erosion power of the Colorado River. Close to the moon's south pole are two canyons each comparable in size to the Grand Canyon that were born in a much different process.
Asteroid impact carved two Grand Canyon-sized valleys on the Moon in under 10 minutes
Scientists found that an asteroid impact carved two massive canyons on the moon in minutes. High-speed debris helped shape the trenches.
How an ancient asteroid strike carved out 2 grand canyons on the moon
New research shows that when an asteroid slammed into the moon billions of years ago, it carved out a pair of grand canyons on the lunar far side.
Two of the Moon's Grand Canyons Were Formed in Just Ten Violent Minutes, New Study Suggests
It didn’t take long for the moon to get its grand canyons. Vallis Schrödinger and Vallis Planck are two long channels near the lunar south pole. The canyons, each more than 160 miles long and around two miles deep,
Massive lunar canyons formed within minutes, most likely due to asteroid strike
Two canyons on the far side of the moon, each as large as Earth's Grand Canyon, formed within less than 10 minutes, most likely due to a massive impact there 3.8bn years ago. The object and its work are the subjects of scientific speculation in the journal Nature Communications.

Asteroid headed towards Earth might smash into the Moon, scientists say
Now, new calculations by University of Arizona astronomer David Rankin have reportedly found that there is a slim chance of about 0.3 per cent of the 90-metre-wide asteroid crashing onto the Moon.
