Summary

The Chicxulub Impactor, also known as the K/Pg impactor and (more speculatively) as the Chicxulub asteroid, was an asteroid or comet at least 10 kilometres (6 miles) in diameter which struck the Earth 66 million years ago creating the Chicxulub crater. It 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 death of the planet's non-avian dinosaurs and many other species.

The impactor's crater is more than 180 km (110 miles) in diameter, making it the third largest known impact crater on Earth.

Geological evidence shows that the impact dates from the end of the Cretaceous, approximately 66 million years ago. The impact is implicated in causing the mass extinction event at that time, as suggested by the K-Pg boundary, the geological boundary between the Cretaceous and Paleogene periods. Some scientists doubt whether the impact was the sole cause, and others debate whether the Chicxulub impactor was one of several that may have struck the Earth at around the same time.

In March 2010, following extensive analysis of the available evidence covering some twenty years' worth of data spanning the fields of palaeontology, geochemistry, climate modelling, geophysics and sedimentology, forty-one international experts from thirty-three institutions reviewed the available evidence and concluded that the impact at Chicxulub triggered the mass extinctions at the K–Pg boundary, including those of the dinosaurs.
