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 ...
The remaining objects of the Solar System (including the four terrestrial planets, the dwarf planets, moons, asteroids, and comets) together comprise less than 0.002% of the Solar System's total mass. [h] The Sun is composed of roughly 98% hydrogen and helium, [41] as are Jupiter and Saturn.
Of the Solar System's eight planets and its nine most likely dwarf planets, six planets and seven dwarf planets are known to be orbited by at least 300 natural satellites, or moons. At least 19 of them are large enough to be gravitationally rounded; of these, all are covered by a crust of ice except for Earth's Moon and Jupiter's Io . [ 1 ]

The Sun, planets, moons and dwarf planets (true color, size to scale, distances not to scale) The following outline is provided as an overview of and topical guide to the Solar System: Solar System – gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the ...
The presumed distance of the Oort cloud compared to the rest of the Solar System. The Sun is a lone, G-type main-sequence star inside the galaxy of the Milky Way, surrounded by eight major planets orbiting the star by the influence of gravity, most of them with a cohort of satellites, or moons, orbiting them.
In an almost poetic twist, the moon is also the most reflective body in the solar system—reflecting almost 100 percent of the light that reaches it. It is a beacon in more ways than one. 4.
Venus to scale among the Inner Solar System planetary-mass objects, arranged by the order of their orbits outward from the Sun (from left: Mercury, Venus, Earth, the Moon, Mars and Ceres) Venus is one of the four terrestrial planets in the Solar System, meaning that it is a rocky body like Earth.
