The orbital motion of planets and stars is calculated in real time, with the ability to accelerate, decelerate, or reverse the flow of time.Possibility of renaming and describing of any object, including procedural ones. Built-in wiki system with descriptions of many known objects and ability to extend by user.Saving locations and autopilot's journal. Scalable map of the Universe and a planetary system browser. Automatic binding of the observer to a moving object and automatic selection of optimum flight speed.'Select and fly' autopilot: just click on any object with the mouse and hit the 'G' key to automatically go directly to the object.Movement with inertia is made possible in Spacecraft mode or Aircraft mode. The observer can move around in space using the WASD keys, like in First Person Shooters.Transition between any celestial body and any scale occurs seamlessly. The observer is free to move around the universe.Uncharted regions of space feature procedurally generated objects: galaxies, stars, star clusters, nebulae and planetary systems.Known celestial objects are represented using data from the catalogs: galaxies (NGC/IC), stars (HIPPARCOS), star clusters, nebulae, planets (our Solar system data and known extrasolar planets).All types of celestial objects are represented: galaxies, nebulae, stars and star clusters, planets and moons, comets and asteroids.Features In this screenshot, every star can be visited by using the WASD keys and mouse. Areas of the known universe are represented using actual astronomical data, while regions uncharted by astronomy are generated procedurally. The program allows players to explore the universe in three dimensions, from planet Earth to the most distant galaxies. SpaceEngine is a free space simulation program and game engine developed by Russian astronomer and programmer Vladimir Romanyuk.
