Jupiter has been called the Solar System's vacuum cleaner [222] because of its immense gravity well and location near the inner Solar System. There are more impacts on Jupiter, such as comets, than on any other planet in the Solar System. [223] For example, Jupiter experiences about 200 times more asteroid and comet impacts than Earth.

The inner Solar System is the region comprising the terrestrial planets and the asteroids. [ 89 ] Composed mainly of silicates and metals, [ 90 ] the objects of the inner Solar System are relatively close to the Sun; the radius of this entire region is less than the distance between the orbits of Jupiter and Saturn.
These probes make Jupiter the most visited of the Solar System's outer planets as all missions to the outer Solar System have used Jupiter flybys. On 5 July 2016, spacecraft Juno arrived and entered the planet's orbit—the second craft ever to do so. Sending a craft to Jupiter is difficult, mostly due to large fuel requirements and the effects ...
Jupiter is by far the largest planet in our solar system. The huge ball of hydrogen and helium circling the sun is about 88,000 miles wide, meaning more than 1,300 Earths could fit inside it.
For these reasons Jupiter has the highest frequency of impacts of any planet in the Solar System, justifying its reputation as the "sweeper" or "cosmic vacuum cleaner" of the Solar System. [7] 2018 studies estimate that between 10 and 65 impacts per year of meteoroids with a diameter of between 5 and 20 meters (16 and 66 ft) can occur on the ...
U.S. customary. ≈ 4.1847 × 1027 pounds. The 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 the planet 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.
The helium abundance is 0.157 ± 0.004 relative to molecular hydrogen by number of molecules, and its mass fraction is 0.234 ± 0.005, which is slightly lower than the Solar System's primordial value. [2] The reason for this low abundance is not entirely understood, but some of the helium may have condensed into the core of Jupiter. [22]
Outline of Jupiter. The following outline is provided as an overview of and topical guide to Jupiter: Jupiter – fifth planet from the Sun and the largest in the Solar System. It is a giant planet with a mass one-thousandth that of the Sun, but two and a half times that of all the other planets in the Solar System combined.
