Chicxulub, about 119 miles (180 km) in diameter and located beneath the northern edge of the Yucatán Peninsula, Mexico, is one of the best preserved The Chicxulub crater isn’t visible on the surface because it is covered by younger, relatively undeformed sediments. It was identified from a nearly circular gravity anomaly along the northwestern edge of the Yucatán Peninsula (Figure 1). 2,3 There’s disagreement on the crater’s exact size, but its diameter is approximately 110 miles—large enough for a six-mile-wide asteroid or 2019-10-11 · The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico.

The crater measures between 180 and 240 kilometres across, indicating an impactor of colossal size, the biggest impact confirmed on Earth.

Cenotes and the Ocean Lake Phenomenon are the positive results of Do you know the Chicxulub Crater? Knowledge of the size and internal structure of the Chicxulub crater is necessary for quantifying the effects of the impact on the Cretaceous environment. Although much information bearing on the crater's structure is available, diameter estimates range from 170 to 300 km (refs 1á¤-7), corresponding to an order of magnitude variation in impact energy.
