  • Chicxulub asteroid, was an asteroid or other celestial body some 11 to 81 kilometres in diameter and having a mass which struck the Earth at the end of the Cretaceous period, 66 million years ago, creating the Chicxulub crater. It impacted a few kilometres 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 coincide, there is a scientific consensus that its impact was the Cretaceous–Paleogene extinction event which caused the death of the planet's non-avian dinosaurs and many other species.In October 2019, researchers reported that the event rapidly acidified the oceans producing ecological collapse and long-lasting effects on the climate, and, accordingly, was a key reason for the Cretaceous–Paleogene extinction event.
