Epicyclic gearing or planetary gearing is a gear system consisting of one or more outer, or planet, gears or pinions, revolving about a central sun gear or sun wheel. [4] [5] Typically, the planet gears are mounted on a movable arm or carrier, which itself may rotate relative to the sun gear.
Add-ons illustrating less well-known internet fiction, like Orion's Arm, or role-playing games, like 2300 AD, and personal works by members of the Celestia community depicting fictional planetary systems with inhabited worlds, spacecraft, cities, and special effects can also be added.

The Ravigneaux gearset is a double planetary gear set, invented by Pol Ravigneaux, who filed a patent application on July 28, 1949, in Neuilly-sur-Seine France. [1] This planetary gear set, commonly used in automatic transmissions, is constructed from two gear pairs, ring–planet and planet–planet. The gearset provides four forward gear ...
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.
FlightGear Flight Simulator (often shortened to FlightGear or FGFS) is a free, open source multi-platform flight simulator developed by the FlightGear project since 1997. [4] David Murr started this project on April 8, 1996. This project had its first release in 1997 and continued in development.
Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.Using 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 ...
Planet c is possibly a potentially habitable Super-Earth but is probably too hot or massive.

However, it is a gas giant, so it itself is uninhabitable although a large moon orbiting ...
Space flight simulators use flight dynamics in a free environment; this free environment lets the spacecraft move within the three-dimensional coordinate system or the x, y, and z (applicate) axis. See Lists of video games for related lists.
