It was formed slightly over 66 million years ago when an asteroid, about ten kilometers (six miles) in diameter, struck Earth. The crater is estimated to be 200 kilometers (120 miles) in diameter and 1 kilometer (0.62 miles) in depth.

2022年4月12日 · On the Earth and Venus, impact structures the size of Chicxulub (around 180–200 km in diameter 14,15,34) are expected to correspond to the crater morphology of a multi-ring basin...

2021年2月15日 · The Chicxulub impactor, as it’s known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep. Its devastating impact brought the reign of the dinosaurs to an abrupt and calamitous end, scientists say, by triggering their sudden mass extinction, along with the end of ...

2016年2月25日 · The new analysis shows that the Chicxulub impact mobilized nearly 48,000 cubic miles of sediment across the gulf. It wiped out the contours of the bottom of the gulf, covering everything from...

At the end of the Cretaceous Period 66 million years ago, an asteroid the size of a city collided with Earth. The Chicxulub impactor, as it is called, was somewhere between 10 and 15...

2019年9月9日 · When an asteroid the size of the Chicxulub impactor, estimated to be more than six miles wide, strikes a planet, material is ripped up from below the surface and tossed into the air,...

1997年12月4日 · The precise size and morphology of the Chicxulub crater has been in dispute; it has been interpreted as a ∼ 180 km peak-ring crater 2, 9, 11, a ∼ 250 km peak-ring crater 5, 8, and a ∼ 300 km...

2014年3月19日 · We found that the kinetic energy of the impactor is in the range from 1.3e24 J to 5.8e25 J. The mass is in the range of 1.0e15 kg to 4.6e17 kg.

Most estimates suggest the Chicxulub asteroid was between 10 to 15 kilometers (6 to 9 miles) in diameter. That’s roughly the size of Mount Everest! Table 1: Estimated dimensions of the Chicxulub asteroid. The speed at which the Chicxulub asteroid struck Earth was mind-boggling.

In this study we obtained an estimation of the most important characteristics of the impactor, which are the size, mass and kinetic energy. We found that the kinetic energy of the impactor is in the range from 1.3x1024 J to 5.8x1025 J. The mass is in the range of 1.0x1015 kg to 4.6x1017 kg.
