List of largest craters in the Solar System

none

Summary

none

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).

Rheasilvia and Veneneia are 95% and 75% of the mean diameter of Vesta, 529 km. However, the mean is affected by the craters themselves. They are 89% and 69% the mean equatorial diameter of 569 km.
