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.

A volcanic crater is a bowl-shaped depression in the ground caused by volcanic activity, usually located above the volcano's vent. [11] During volcanic eruptions, molten magma and volcanic gases rise from an underground magma chamber, through a conduit, until they reach the crater's vent, from where the gases escape into the atmosphere and the magma is erupted as lava.
This is a list of officially named craters in the Solar System as named by IAU's Working Group for Planetary System Nomenclature.As of 2017, there is a total of 5,223 craters on 40 astronomical bodies, which includes minor planets (asteroids and dwarf planets), planets, and natural satellites. [1]
Following are the largest impact craters on various worlds of the Solar System.For a full list of named craters, see List of craters in the Solar System.The ratio column compares the crater diameter with the diameter of the impacted celestial body.
The Yuty crater is an example of a Rampart crater so called because of the rampart like edge of the ejecta. In the Yuty crater the ejecta completely covers an older crater at its side, showing that the ejected material is just a thin layer. [36]
At Cap d’Erquy, along the northern coast of France, the satellite system picked up on potential structures buried into a crater, according to the release, and the researchers took a closer look.
Compared to other bodies in our Solar System, Earth's moon isn't particularly huge. However, its relatively small size belies one of its most interesting features, which is a colossal crater ...
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]
