Mead crater is the largest impact crater on Venus, with a diameter of 280 km (174 miles). [1] The crater has an inner and an outer ring and a small ejecta blanket surrounding the outer ring. Mead crater is relatively shallow (likely due to viscous relaxation [2] and infilling) and crater floor looks very similar in morphology to the surrounding ...
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 maximum crater diameter is 157% of the body diameter (the circumference along a great circle).
The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.
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.

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]
The surface of Venus is comparatively flat. When 93% of the topography was mapped by Pioneer Venus Orbiter, scientists found that the total distance from the lowest point to the highest point on the entire surface was about 13 kilometres (8.1 mi), about the same as the vertical distance between the Earth's ocean floor and the higher summits of the Himalayas.
The Batagay crater, sometimes referred to as Batagaika or the "gateway to hell," represents a much larger, often invisible problem that affects the entire planet. What is this hole in Siberia?
The geology of solar terrestrial planets mainly deals with the geological aspects of the four terrestrial planets of the Solar System – Mercury, Venus, Earth, and Mars – and one terrestrial dwarf planet: Ceres. Earth is the only terrestrial planet known to have an active hydrosphere. Terrestrial planets are substantially different from the ...
