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]
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]
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.
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.
crater wall, the downward-sloping portion of the crater crater floor, a more or less smooth, flat area, which as it ages accumulates small craters of its own central peak, found only in some craters with a diameter exceeding 26 km (16 mi); this is generally a splash effect caused by the kinetic energy of the impacting object being turned to ...
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 ...
Tycho is a relatively young crater, with an estimated age of 108 million years , based on analysis of samples of the crater ray recovered during the Apollo 17 mission. [3] This age initially suggested that the impactor may have been a member of the Baptistina family of asteroids, but as the composition of the impactor is unknown this remained ...
