These lists contain the Sun, the planets, dwarf planets, many of the larger small Solar System bodies (which includes the asteroids), all named natural satellites, and a number of smaller objects of historical or scientific interest, such as comets and near-Earth objects.
Euler diagram showing the types of bodies orbiting the Sun. The following is a list of Solar System objects by orbit, ordered by increasing distance from the Sun.Most named objects in this list have a diameter of 500 km or more.
Animation of Saturn and the Solar System's outer planets orbiting around the Sun Simulated appearance of Saturn as seen from Earth (at opposition) during an orbit of Saturn, 2001–2029 The average distance between Saturn and the Sun is over 1.4 billion kilometers (9 AU ).
Careful observations of the 1769 transit of Venus allowed astronomers to calculate the average Earth–Sun distance as 93,726,900 miles (150,838,800 km), only 0.8% greater than the modern value. [291] Uranus, having occasionally been observed since 1690 and possibly from antiquity, was recognized to be a planet orbiting beyond Saturn by 1783. [292]
Orbiting the planet at 3.5 million km, it is by far the most distant of Saturn's large moons, and also has the largest orbital inclination, at 15.47°. [45] Iapetus has long been known for its unusual two-toned surface; its leading hemisphere is pitch-black and its trailing hemisphere is almost as bright as fresh snow. [ 80 ]
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.
Moons of other planets are spewing forth plumes that could contain extraterrestrial life. ... The oceans of some moons orbiting Saturn and Jupiter are key places for the search for alien life.
Neptune has 16 known moons; the largest, Triton, accounts for more than 99.5 percent of all the mass orbiting the planet. Triton is large enough to have achieved hydrostatic equilibrium, but, uniquely for a large moon, has a retrograde orbit, suggesting it was a dwarf planet that was captured.
