There is broad consensus that the Chicxulub impactor was a C-type asteroid with a carbonaceous chondrite-like composition, rather than a comet. [29] [67] These types of asteroids originally formed in the outer Solar System, beyond the orbit of Jupiter. [67]
She noted that research into the Yucatan asteroid strike, also known as the Chicxulub impact crater, suggests a shift during less than a quarter of a century. And, previous investigations into the ...
A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the extinction of nearly ... The asteroid was huge — likely between 6 and 9 miles (9.7 and ...
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 ...
Evidence indicates that the asteroid fell in the Yucatán Peninsula, at Chicxulub, Mexico. The hypothesis is named after the father-and-son team of scientists Luis and Walter Alvarez, who first suggested it in 1980. Shortly afterwards, and independently, the same was suggested by Dutch paleontologist Jan Smit. [2]
This impactor excavated the Chicxulub crater that is 180 km (110 mi) in diameter. With an object this size, dust and debris would still be ejected into the atmosphere even if it hit the ocean, which is only 4 km (2.5 mi) deep. [3] An asteroid, meteor, or comet would remain intact through the atmosphere by virtue of its
However, the most widely accepted theory for the mass extinction is that an asteroid (or, perhaps a comet) at least 10 kilometers in diameter crashed near modern-day Chicxulub on the Yucatán ...
The Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico. [10] Its center is located near the town of Chicxulub, after which the crater is named. [11] It was formed by a large asteroid or comet about 10–15 km (6.2–9.3 mi) in diameter, [12] [13] the Chicxulub impactor, striking the Earth. The date of the ...
