All known dwarf planets and dwarf planet candidates have prograde orbits around the Sun, but some have retrograde rotation. Pluto has retrograde rotation; its axial tilt is approximately 120 degrees. [9] Pluto and its moon Charon are tidally locked to each other. It is suspected that the Plutonian satellite system was created by a massive ...
A number of smaller groups distinct from the asteroid belt; The outer Solar System with the giant planets, their satellites, trojan asteroids and some minor planets. Jupiter. Rings of Jupiter; Complete list of Jupiter's natural satellites. Galilean moons. Io; Europa; Ganymede; Callisto; Jupiter trojans; Jupiter-crossing minor planets; Saturn ...
Orbits around the L 1 point are used by spacecraft that want a constant view of the Sun, such as the Solar and Heliospheric Observatory. Orbits around L 2 are used by missions that always want both Earth and the Sun behind them. This enables a single shield to block radiation from both Earth and the Sun, allowing passive cooling of sensitive ...
Orbits of planets are to scale, but the orbits of moons and the sizes of bodies are not. The term "Solar System" entered the English language by 1704, when John Locke used it to refer to the Sun, planets, and comets. [288] In 1705, Halley realized that repeated sightings of a comet were of the same object, returning regularly once every 75–76 ...
The inclination and semi-major axis are represented on the Y and X-axis, respectively. The satellites with inclinations below 90° are prograde, those above 90° are retrograde. The X-axis is labeled in terms of Saturn's Hill radius. The Gallic group is a dynamical grouping of the prograde irregular satellites of Saturn following similar orbits.
Five planets are going to be retrograde in the summer of 2024. Here are the dates for Mercury retrograde, Venus retrograde, Saturn retrograde, Neptune retrograde, Pluto retrograde and more.
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.
The new discovery increases the moons orbiting the "jewel of our solar system" to 82, surpassing Jupiter
