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).
