An animation showing the Chicxulub impact and subsequent crater formation. The impactor's velocity was estimated at 20 kilometers per second (12 mi/s). [30] The kinetic energy of the impact was estimated at 72 teratonnes of TNT (300 ZJ). [31]
The Chicxulub crater is an impact crater buried underneath the Mexican Yucatán Peninsula, with its center located offshore, near the town of Chicxulub.The crater is about 180 kilometers (110 mi) in diameter, making it one of the largest confirmed impact structures in the world; the asteroid whose impact (animation shown) formed the crater was at least 10 km (6 mi) in diameter.
An animation modelling the impact, and subsequent crater formation of the Chicxulub impact (University of Arizona, Space Imagery Center) The prehistoric Chicxulub impact, 66 million years ago, believed to be the cause of the Cretaceous–Paleogene extinction event, was caused by an asteroid estimated to be about 10 kilometres (6.2 mi) wide.

A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin.. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium ...
A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the extinction of nearly all dinosaurs 66 million years ago.
Uniquely, Tanis appears to record in detail, extensive evidence of the direct effects of the giant Chicxulub asteroid impact which struck the Gulf of Mexico 66.043 million years ago, and wiped out all non-avian dinosaurs and many other species (the so-called "K–Pg" or "K–T" extinction).
