Chicxulub impactor - Wikipedia, the free encyclopedia:
"The Chicxulub impactor (pron.: /ˈtʃiːkʃəluːb/ cheek-shə-loob), also known as the K/Pg impactor and (more speculatively) as the Chicxulub asteroid, was an asteroid or comet at least ten kilometres (six miles) in diameter which impacted a few miles from the present-day town of Chicxulub in Mexico, after which the impactor and its crater are named. Because the estimated date of the object's impact and the Cretaceous–Paleogene boundary (K–Pg boundary) coincide, there is a scientific consensus that its impact was the Cretaceous–Paleogene extinction event which caused the demise of the planet's nonavian dinosaurs and other species."
