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 ...
720,000 km/h (450,000 mi/h) [ 10] Orbital period. ~230 million years [ 10] The Solar System[ d] is the gravitationally bound system of the Sun and the objects that orbit it. [ 11] It was formed about 4.6 billion years ago when a dense region of a molecular cloud collapsed, forming the Sun and a protoplanetary disc.
Orrery. A small orrery showing Earth and the inner planets. An orrery is a mechanical model of the Solar System that illustrates or predicts the relative positions and motions of the planets and moons, usually according to the heliocentric model. It may also represent the relative sizes of these bodies; however, since accurate scaling is often ...
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 ...
English: Anyway in this video... to roughly explain the tilts: we think they started out roughly the same in tilt, so either by huge impacts, tidal forces or planetary migration the tilts have been changed. The reason why larger planets tend to spin faster is because they took on more of the Sun-orbiting mass, adding the mass's orbital motion ...
Vector graphics. Vector graphics are a form of computer graphics in which visual images are created directly from geometric shapes defined on a Cartesian plane, such as points, lines, curves and polygons. The associated mechanisms may include vector display and printing hardware, vector data models and file formats, as well as the software ...
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.
