Most Massive Planets in the Solar System
Key Findings
About This Dataset
Most Massive Planets in the Solar SystemJupiter is the undisputed giant, with a mass of 317.8 Earths, more than twice that of all the other planets combined. Saturn (95.2 Earth masses) is a distant second, and together these two gas giants hold the overwhelming majority of the planetary mass in the Solar System. The ice giants Neptune (17.1) and Uranus (14.5) form a middle group, notably far less massive than the gas giants despite also being large worlds. The four rocky inner planets are tiny by comparison: Earth is the benchmark at 1.0, while Venus (0.815), Mars (0.107) and Mercury (0.055) trail well behind. The enormous gap, Jupiter is nearly 6,000 times more massive than Mercury, reflects how the giant planets captured vast amounts of gas early in the Solar System's history while the inner worlds stayed small and rocky.
