The Chicxulub crater is more than 180 km (110 mi) in diameter, making it the third largest confirmed impact crater. Petroleum prospectors found it in the late 1970s. The bolide which formed the crater was at least 10 km (6 mi) in diameter.

The ~320-km-diameter crater contains an ~150-km-diameter peak ring that rises up to 2.5 km above the cra - ter floor (Shoemaker et al., 1994).

[1] 170 kilométeres átmérőjével az ismert becsapódási kráterek közül a közepes méretűek közé tartozik. Chicxulub crater formed ~ 66 Ma ago by an asteroid impact on the Yucatan platform in the southern Gulf of Mexico. The crater has a ~ 200 km rim diameter and has been covered by carbonate sediments ~80 km in diameter and extending several hundred meters above the buried crater floor.

The Chicxulub impactor, also known as the K/Pg impactor or as the Chicxulub asteroid, was the asteroid or other celestial body that struck Earth about 66 million years ago, creating the Chicxulub crater and, according to scientific consensus, acting as the main cause of the Cretaceous–Paleogene extinction event. The impactor is typically estimated to have been an asteroid with a diameter of about 15 km, but its composition and size remain a topic of debate among experts.
