The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. It was formed by a large asteroid or comet about 11 to 81 kilometres (6.8 to 50.3 miles) in diameter slightly less than 66 million years ago. The event was the cause of the Cretaceous–Paleogene extinction event, a mass extinction in which 75% of plant and animal species on Earth became extinct, including all non-avian dinosaurs.
Five monks from Canterbury reported to the abbey's chronicler, Gervase, that shortly after sunset on June 18, 1178, they observed "the upper horn [of the moon] split in two.” What they saw was possibly the Giordano Bruno crater being formed.
It is believed that the current oscillations of the Moon's distance from the Earth are a result of the collision that the monks witnessed.
The largest crater on the moon measures 183 miles across.
Korolev crater on Mars is 50 miles wide, contains 530 cubic miles of water ice (as much as the Great Bear Lake in northern Canada), and in the center of the crater the ice is more than a mile thick

Pharos, the largest impact crater on Neptune's moon Proteus, is more than half the diameter of Proteus itself.
