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.
SpaceEngine is an interactive 3D planetarium and astronomy software [2] initially developed by Russian astronomer and programmer Vladimir Romanyuk. [3] Development is now continued by Cosmographic Software, an American company founded by Romanyuk and the SpaceEngine Team in February 2022, based in Connecticut.
A live simulation, by definition represents the highest fidelity, since it is reality. But a simulation quickly becomes more difficult when it is created from various live, virtual and constructive elements, or sets of simulations with various network protocols, where each simulation consists of a set of live, virtual and constructive elements.
Celestia allows users to navigate at different speeds, and allow users to orbit stars, planets, moons, and other space objects, track space objects such as spacecraft, asteroids, and comets as they fly by, or travel to and/or fly through galaxies. Light time delay is an optional function.
This is the boundary of the Solar System to interstellar space. The outermost region of the Solar System is the theorized Oort cloud, the source for long-period comets, extending to a radius of 2,000–200,000 AU. The closest star to the Solar System, Proxima Centauri, is 4.25 light-years (269,000 AU) away.
An N-body simulation of the cosmological formation of a cluster of galaxies in an expanding universe. In physics and astronomy, an N-body simulation is a simulation of a dynamical system of particles, usually under the influence of physical forces, such as gravity (see n-body problem for other applications).

Artistic view of Deep Space 1, showing both the solar panels and ion engine (with blue exhaust), major aspects of this solar electric design. Solar energy may also be temporarily stored in chemical batteries inside the spacecraft bus. The Dawn spacecraft's xenon tank prior to integration with spacecraft. The xenon was the propellant for the ...
