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 ...
1.2 km permanent; walkable (est. 2016) The Thousand-Yard Model [54] [55] (virtual) 1:6,336,000,000 0.2 m 0.2 cm 25 m 1 km The scale of the planets is the same as the scale between them, and the planets are represented by everyday objects; the Earth is a peppercorn, Jupiter is a walnut, and Neptune is a coffee bean.

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 ...
Terrestrial planet. The four terrestrial planets of the Solar System : Mercury and Venus. Earth and Mars. Not shown to scale. A terrestrial planet, telluric planet, or rocky planet, is a planet that is composed primarily of silicate, rocks or metals. Within the Solar System, the terrestrial planets accepted by the IAU are the inner planets ...
The Pajamäki Solar System Scale Model is a scale model of the Solar System built in Helsinki and partly in Espoo, Finland in 1992. Its scale is 1:1 000 000 000, i.e. one to one billion, so that 1 millimeter in the model corresponds to 1 000 kilometers in the actual Solar System. The coordinates given for the model are those for the Sun in ...
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 ...
The Atlas of Terrestrial Group Planets and their Moons ( Russian: Атлас планет Земной группы и их спутников) is a Soviet -era planetary atlas published in the Russian language in Moscow. It summarizes Soviet and American planetary science results in thematic maps of Mercury, Venus, the Moon, Mars, Phobos, and ...
There are eight planets within the Solar System; planets outside of the solar system are also known as exoplanets . Artist's concept of the potentially habitable exoplanet Kepler-186f. As of 25 July 2024, there are 5,741 confirmed exoplanets in 4,285 planetary systems, with 960 systems having more than one planet. [1]
