For eroded or buried craters, the stated diameter typically refers to the best available estimate of the original rim diameter, and may not correspond to present surface features. Time units are either in ka (thousands) or Ma (millions) of years.

Craters with diameter or more are all older than 10 Ma, except possibly Karakul, , whose age is uncertain. There are more than forty craters of such size. The largest two within the last hundred million years have been linked to two extinction events: Chicxulub for the Cretaceous–Paleogene and the Popigai impact for the

Craters by continent

, the Earth Impact Database (EID) contains 190 confirmed craters. (As of 2022, no update has yet been made to the database.) The table below is arranged by the continent's percentage of the Earth's land area, and where Asian and Russian craters are grouped together per EID convention. The global distribution of known impact structures apparently shows a surprising asymmetry,Prezzi, Claudia B.; Orgeira, María Julia; Acevedo, Rogelio D.; Ponce, Juan Federico; Martinez, Oscar; Rabassa, Jorge O.; Corbella, Hugo; Vásquez, Carlos; González-Guillot, Mauricio; Subías, Ignacio; (2011)
