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 ...
SpaceEngine creates a 1:1 scale three-dimensional planetarium representing the entire observable universe, combining real astronomical data with scientifically accurate procedural generation algorithms. Users can travel through space in any direction or at any speed and can move forwards or backwards in time. [4]
Relative masses of the Solar planets. Jupiter at 71% of the total and Saturn at 21% dominate the system. Relative masses of the solid bodies of the Solar System. Earth at 48% and Venus at 39% dominate. Bodies less massive than Pluto are not visible at this scale. Relative masses of the rounded moons of the Solar 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 ...
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 ...
Matrioshka brain. A matrioshka brain[ 1][ 2] is a hypothetical megastructure of immense computational capacity powered by a Dyson sphere. It was proposed in 1997 by Robert J. Bradbury (1956–2011 [ 3] ). It is an example of a class-B stellar engine, employing the entire energy output of a star to drive computer systems. [ 4]
Celestia is a real-time 3D astronomy software program that was created in 2001 by Chris Laurel. The program allows users to virtually travel through the universe and explore celestial objects that have been catalogued. Celestia also doubles as a planetarium, but the user is not restricted to the Earth's surface, like in other planetarium ...
The Scale of the Universeis an interactive online visualization tool first created in 2010 by Cary and Michael Huang, two brothers from Moraga, California. [1][2][3][4][5]Released on both Newgroundsand the Huang brothers' personal web page, it features a scrollbarthat players can use to navigate through orders of magnitudeand view various ...
