The hypothesis can be applied to multiple phenomena in the Solar System. The "Mars problem" is a conflict between some simulations of the formation of the terrestrial planets which end with a 0.5–1.0 MEarth planet in its region, much larger than the actual mass of Mars: 0.107 MEarth, when begun with planetesimals distributed throughout the inner Solar System.
