how does the mass of jupiter compare to the mass of all the other planets combined
Jupiter mass Jupiter mass, also called Jovian mass is the unit of mass equal to the total mass of the planet Jupiter. This value may refer to the mass of planet Jupiter alone, or the mass of the entire Jovian system to include the Moons of Jupiter. Jupiter is by far the most massive planet in the solar system. It is approximately 2.5 times more massive than all of the other planets in the Solar System combined.[2]
Earth mass Earth mass (M⊕, where ⊕ is the standard astronomical symbol for planet Earth) is the unit of mass equal to that of Earth. This value includes the atmosphere but excludes the moon. The current best estimate for Earth mass is M⊕ = 7024597220000000000♠(5.9722±0.0006)×1024 kg.[1][2] Earth mass is a standard unit of mass in astronomy that is used to indicate the masses of other planets, including rocky terrestrial planets and exoplanets.
