They proposed that the Chicxulub asteroid was also a member of this group. [69] Subsequent evidence has cast doubt on this theory. A 2009 spectrographic analysis revealed that 298 Baptistina has a different composition more typical of an S-type asteroid than the presumed carbonaceous chondrite composition of the Chicxulub impactor.

A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the ... (9.7 and 14.5 kilometers) in diameter. But its colossal size is why it largely ...
One is about 100 microns in size (Natalie Cheng / Bridget Wade) She noted that research into the Yucatan asteroid strike, also known as the Chicxulub impact crater, suggests a shift during less ...
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
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]
The meteorite was estimated to have been up to 200 times larger than the extinction-inducing Chicxulub asteroid. That massive size made it plenty large enough to trigger a devastating tsunami that ...
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 ...
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 ...
