    Parts-per-million chart of the relative mass distribution of the Solar System, each cubelet denoting 2 × 10 24 kg. This article includes a list of the most massive known objects of the Solar System and partial lists of smaller objects by observed mean radius. These lists can be sorted according to an object's radius and mass and, for the most ...

  3. Solar System - Wikipedia

    en.wikipedia.org/wiki/Solar_System

    The orbits of Solar System planets are nearly circular. Compared to many other systems, they have smaller orbital eccentricity. [70] Although there are attempts to explain it partly with a bias in the radial-velocity detection method and partly with long interactions of a quite high number of planets, the exact causes remain undetermined. [70] [74]

    Jupiter has been called the Solar System's vacuum cleaner [217] 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. [218] For example, Jupiter experiences about 200 times more asteroid and comet impacts than Earth. [66]

    The planet's density is the second highest in the Solar System at 5.427 g/cm 3, only slightly less than Earth's density of 5.515 g/cm 3. [4] If the effect of gravitational compression were to be factored out from both planets, the materials of which Mercury is made would be denser than those of Earth, with an uncompressed density of 5.3 g/cm 3 ...
