Did you know impacts can displace enough mass to change the polls on the moon?

“As asteroid impacts excavated mass, leaving depressions in the surface — or pockets of lower mass — the Moon reoriented itself to bring those pockets toward the poles, while bringing areas of higher mass out toward the equator via centrifugal force. It’s the same force that acts on dough when a pizza maker tosses and spins it in the air to stretch it out.” -William Steigerwald, SEP 19, 2022 NASA Explore
