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 ...
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.
Planetary cartography, or cartography of extraterrestrial objects ( CEO ), is the cartography of solid objects outside of the Earth. Planetary maps can show any spatially mapped characteristic (such as topography, geology, and geophysical properties) for extraterrestrial surfaces. [1] Some well-known examples of these maps have been produced by ...
Around all is a sphere of stars, which rotates. The Tychonic system (or Tychonian system) is a model of the universe published by Tycho Brahe in 1588 [ 1 ], which combines what he saw as the mathematical benefits of the Copernican system with the philosophical and "physical" benefits of the Ptolemaic system. The model may have been inspired by ...
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 number of dwarf planets in the Solar System is unknown. Estimates have run as high as 200 in the Kuiper belt [1] and over 10,000 in the region beyond. [2] However, consideration of the surprisingly low densities of many large trans-Neptunian objects, as well as spectroscopic analysis of their surfaces, suggests that the number of dwarf planets may be much lower, perhaps only nine among ...

A group of the world's leading planet formation experts decided at a conference in 2006 [8] on the following definition of a planetesimal: A planetesimal is a solid object arising during the accumulation of orbiting bodies whose internal strength is dominated by self-gravity and whose orbital dynamics is not significantly affected by gas drag ...
