Chicxulub impactor Chicxulub impactor The Chicxulub impactor ( ), also known as the K/Pg impactor and (more speculatively) as the Chicxulub asteroid, was an asteroid or other celestial body some in diameter which struck the Earth at the end of the Cretaceous period, approximately 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
Kearons (crater) Kearons (crater) Kearons is a small lunar impact crater that is located on the far side of the Moon, to the northwest of the Mare Orientale impact basin, in the outer skirt of ejecta that surrounds the Montes Cordillera range. It is a relatively isolated crater, possibly because any nearby features have been buried under the ejecta. Some distance to the south is the crater Lewis, and to the north-northeast lies Grachev. The rim of this crater forms a rounded polygon, with a sharp edge that has a small craterlet across the northwestern side. The inner wall and interior floor
