English: Planets and dwarf planets of the solar system with sizes shown to scale, but with distances extremely compressed. Orbital planes have been altered with similar artistic license to line up planets and dwarf planets in separate rows.
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 ...
Solar System models, especially mechanical models, called orreries, that illustrate the relative positions and motions of the planets and moons in the Solar System have been built for centuries. While they often showed relative sizes, these models were usually not built to scale. The enormous ratio of interplanetary distances to planetary ...
If the Sun–Neptune distance is scaled to 100 meters (330 ft), then the Sun would be about 3 cm (1.2 in) in diameter (roughly two-thirds the diameter of a golf ball), the giant planets would be all smaller than about 3 mm (0.12 in), and Earth's diameter along with that of the other terrestrial planets would be smaller than a flea (0.3 mm or 0. ...
All planets orbit the Sun in elliptical orbits (image on the left) and not perfectly circular orbits. [71] The radius vector joining the planet and the Sun has an equal area in equal periods. [72] The square of the period of the planet (one revolution around the Sun) is proportional to the cube of the average distance from the Sun. [73]
The observable universe is a ball-shaped region of the universe consisting of all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion.
English: Major bodies orbiting the Sun of the Solar System. Size and distance are set to different scales (i.e., size is grossly exaggerated compared to distance). Outward from the Sun at the left, the objects are Mercury, Venus, Earth, Mars, Ceres (within Asteroid Belt), Jupiter, Saturn, Uranus, Neptune and Pluto-Charon System.
List of planet types. From top to bottom: Mercury, Venus without its atmosphere, Earth and the Moon, Mars, Jupiter, Saturn, Uranus, and Neptune in false colour (not to scale) The following is a list of planet types by their mass, orbit, physical and chemical composition, or by another classification. The IAU defines that a planet in the Solar ...
