Earth is not the only planet with a geologic history, as formal system have been developed for the Moon, Mars, and and Mercury. Meanwhile, attempts have been made in the past for a standardized Venusian scale, and various other solar system bodies could have their histories traced as well. Saturn's moon Titan could be a target for future scale creation due to its candidacy as a celestial body harboring life and the standing liquid on its surface that includes seas, lakes, and rivers. Of course, extrasolar planets could also have scales created for them if enough information is ever known.
