Evolution of Planetary surfaces

The predominant surface modification processes of major solid solar system bodies are shown in this plot. Bodies closer to the origin have more craters, while bodies further away from the origin show more modification. Planet sizes have been rescaled to show surface detail. Scale is relative logarithmic.
