Size of Jupiter compared to Earth and Earth's Moon. Jupiter is about ten times larger than Earth (11.209 R 🜨) and smaller than the Sun (0.102 76 R ☉). Jupiter's mass is 318 times that of Earth; [2] 2.5 times that of all the other planets in the Solar System combined.
The sizes and masses of many of the moons of Jupiter and Saturn are fairly well known due to numerous observations and interactions of the Galileo and Cassini orbiters; however, many of the moons with a radius less than ~100 km, such as Jupiter's Himalia, have far less certain masses. [5]
The sizes are listed in units of Jupiter radii (R J, 71 492 km).This list is designed to include all planets that are larger than 1.6 times the size of Jupiter.Some well-known planets that are smaller than 1.6 R J (17.93 R 🜨 or 114 387.2 km) have been included for the sake of comparison.
Thus, the Sun occupies 0.00001% (1 part in 10 7) of the volume of a sphere with a radius the size of Earth's orbit, whereas Earth's volume is roughly 1 millionth (10 −6) that of the Sun. Jupiter, the largest planet, is 5.2 AU from the Sun and has a radius of 71,000 km (0.00047 AU; 44,000 mi), whereas the most distant planet, Neptune, is 30 AU ...
Earth mass (M E) is the unit of mass equal to that of the Earth. 1 M E = 5.9742 × 10 24 kg. Earth mass is often used to describe masses of rocky terrestrial planets. It is also used to describe Neptune-mass planets. One Earth mass is 0.003 15 times a Jupiter mass.
The sun, Earth and Jupiter will nearly align perfectly in the solar system on Monday, Sept. 26, during an event that happens once every 13 months called the Jupiter opposition.
<p>Jupiter is the largest planet in our Solar System, and the competition really isn't even close. It's an absolutely massive planet and it helped define what a gas giant planet truly is. Because ...
The total mass of heavy elements other than hydrogen and helium in the planet is between 11 and 45 M E. [11] The bulk of the hydrogen on Jupiter is solid hydrogen. [12] Evidence suggests that Jupiter contains a central dense core. If so, the mass of the core is predicted to be no larger than about 12 M E. The exact mass of the core is uncertain ...
