Kaali Crater Field. Zooming in on the location of the huge buried crater formed by the asteroid that wiped out the dinosaurs 65 million years ago. The giant asteroid, believed to be the size of Mount Everest, smashed into the Earth at a point now known as the Chicxulub crater. The crater measures between 180 and 240 kilometres across, The crater is the result of an impact of a 40- to 50-meter iron-nickel asteroid roughly 50,000 years ago. The crater's diameter and depth are believed to be 110 miles (180 kilometers) and 12 miles (20 kilometers), respectively. . We should see smaller fragments coming to Earth more frequently from the Oort cloud, Loeb said. The Chicxulub Crater, named after the village which lies near its center, spans over 110 miles wide, with about half of it resting below the Caribbean Sea. Jupiter kicks these incoming long-period comets into orbits that bring them very close to the sun.. [11]:20, Penfield presented his findings to Pemex, who rejected the crater theory, instead deferring to findings that ascribed the feature to volcanic activity. Easy to use. Its center is located near the town of Chicxulub, after which the crater is named. difficult for many terrestrial animals. [27] In 1998, a 2.5-millimeter (0.098in) meteorite was described from the North Pacific from sediments spanning the CretaceousPaleogene boundary; it was suggested to represent a fragment of the Chicxulub impactor. [3][4] The main evidence of such an impact was contained in a thin layer of clay present in the CretaceousPaleogene boundary (KPg boundary) in Gubbio, Italy. Google hasn't just paid tribute to the Chicxulub crater with its search engine, but the company has also dedicated a section on Google Earth to the historic site. Such rings are only observed near large craters, on the Moon as well as on Mars or Mercury.On Earth, apart from the Chicxulub astrobleme, only two other craters are large enough to have, in theory, concentric rings: Vredefort, in South Africa, and Sudbury, in Canada.However, the latter two are respectively 2 billion and 1.8 billion years old.
