On the territory of which country is the Chicxulub crater located?

The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. Its center is located offshore near the communities of Chicxulub Puerto and Chicxulub Pueblo, after which the crater is named. It was formed when a large asteroid, about 10 kilometers (6.2 miles) in diameter, struck the Earth. The date of the impact coincides precisely with the Cretaceous–Paleogene boundary, slightly more than 66 million years ago, and a widely accepted theory is that worldwide climate disruption from 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.

The crater is estimated to be 150 kilometers (93 miles) in diameter and 20 kilometers (12 miles) in depth. It is the second largest confirmed impact structure on Earth. The crater was discovered by Antonio Camargo and Glen Penfield, geophysicists who had been looking for petroleum in the Yucatán Peninsula during the late 1970s.

A 2020 study concluded that the Chicxulub crater was formed by an inclined (45–60° to horizontal) impact from the northeast.
