The depth of an impact crater in a solid planet or moon may be measured from the local surface to the bottom of the crater, or from the rim of the crater to the bottom. Crater depth diagram. The diagram above shows the full (side) view of a typical crater. Depth "A" measures from the surface to the bottom of the crater. Depth "B" measures from ...

The following tables list geological features on Earth that are known impact events as well as possible, but for which there is currently no confirming scientific evidence in the peer-reviewed literature, impact events. In order for a structure to be confirmed as an impact crater, it must meet a stringent set of well-established criteria. Some ...
The rim of Endurance Crater on Mars, as seen from the landing site of the Opportunity rover. Large craters are those with a diameter greater than 2.3 km, and are distinguished by central uplifts within the impact zone. [1] These larger (also called “complex”) craters can form rims up to several hundred meters in height.
[6] The Weaubleau structure is one of the fifty largest known impact structures on earth and the fourth largest in the United States. The three larger ones in the US either have been glaciated and buried (Manson crater), are under water (Chesapeake Bay crater), or have been subjected to orogeny (Beaverhead impact structure).
An impact crater is a depression in the surface of a solid astronomical body formed by the hypervelocity impact of a smaller object. In contrast to volcanic craters , which result from explosion or internal collapse, [ 2 ] impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. [ 3 ]
If the team can determine the site is a crater formed by an ancient impact event, then the next step is researching just when it happened. Of the world’s roughly 200 impact craters, 31 are ...
A central-peak crater is the most basic form of complex crater. A central-peak crater can have a tightly spaced, ring-like arrangement of peaks, thus be a peak ring crater, though the peak is often single. [3] Central-peak craters can occur in impact craters via meteorites. An Earthly example is Mistastin crater, in Canada. [1]
