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]
Inferior and superior planets In the Solar System, a planet is said to be inferior or interior with respect to another planet if its orbit lies inside the other planet's orbit around the Sun. In this situation, the latter planet is said to be superior to the former. In the reference frame of the Earth, in which the terms were originally used, the inferior planets are Mercury and Venus, while the superior planets are Mars, Jupiter, Saturn, Uranus and Neptune. Dwarf planets like Ceres or Pluto and most asteroids are 'superior' in the sense that they almost all orbit outside the orbit of Earth.
