Universe Sandbox is a series of simulation video games.In Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe, such as moons, planets, asteroids, comets, and black holes.
To calculate the accelerations the gravitational attraction of each body on each other body is to be taken into account. As a consequence the amount of calculation in the simulation goes up with the square of the number of bodies: Doubling the number of bodies increases the work with a factor four.
This is a sourced index of commercial space flight simulation games.The list is categorized into four sections: space flight simulators, space flight simulators with an added element of combat, space combat simulators with an added element of trading, and unreleased space flight simulators.
The choice of solar mass, M ☉, as the basic unit for planetary mass comes directly from the calculations used to determine planetary mass.In the most precise case, that of the Earth itself, the mass is known in terms of solar masses to twelve significant figures: the same mass, in terms of kilograms or other Earth-based units, is only known to five significant figures, which is less than a ...
The game models the Gaia hypothesis of James Lovelock (who assisted with the design and wrote an introduction to the manual), and one of the options available to the player is the simplified "Daisyworld" model. [4] SimEarth screenshot, IBM PC version. In this simulated planet, radiates have developed sapience and are beginning to form ...
The TOP2013 solution is the best for the motion over the time interval −4000...+8000. Its precision is of a few 0.1″ for the four planets, i.e. a gain of a factor between 1.5 and 15, depending on the planet, compared to VSOP2013. The precision of the theory of Pluto remains valid up to the time span from 0 to +4000. [9]
OpenUniverse is a 3D Solar System simulator created by Raúl Alonso Álvarez. It uses OpenGL 1.1 (implemented through Mesa 3D) to simulate the Solar system in complete 3D, including its planets and their major and minor moons, along with a few asteroids with real 3D models created from real data.
Orbiter was developed as a simulator, [14] with accurately modeled planetary motion, gravitation effects (including non-spherical gravity), free space, atmospheric flight and orbital decay. [15] [16] The position of the planets in the solar system is calculated by the VSOP87 solution, while the Earth-Moon system is simulated by the ELP2000 ...
