About SpaceEngine

SpaceEngine is a realistic virtual Universe you can explore on your computer. You can travel from star to star, from galaxy to galaxy, landing on any planet, moon, or asteroid with the ability to explore its alien landscape. You can alter the speed of time and observe any celestial phenomena you please. All transitions are completely seamless, and this virtual universe has a size of billions of light-years across and contains trillions upon trillions of planetary systems. The procedural generation is based on real scientific knowledge, so SpaceEngine depicts the universe the way it is thought to be by modern science. Real celestial objects are also present if you want to visit them, including the planets and moons of our Solar system, thousands of nearby stars with newly discovered exoplanets, and thousands of galaxies that are currently known.

Capabilities

Feature	Description
EXPLORE THE ENTIRE UNIVERSE	FORGET ABOUT SPACE AND TIME RESTRICTIONS
BECOME A PIONEER WITH SPACEENGINE	All types of celestial objects represented: Galaxies, nebulae, stars and star clusters, planets and moons, comets and asteroids.
Thousands of known celestial objects	Known galaxies, stars, planets, asteroids, nebulae are represented using catalogs: HIPPARCOS, NGC/IC, Messier, MPC, NASA Exoplanet Archive and many others.
procedural generation	For uncharted regions. Uncharted regions of space feature procedurally generated objects: galaxies, stars, star clusters, nebulae and planetary systems.
Incredibly huge and realistic Universe	Trillions of galaxies with billions of star systems in each, everything is realistically scaled.
free to move around the universe	Seamless transition from the surface of a planet to the most distant galaxies, and free game-like movement with the WASD keys.
Easy navigation	Many useful tools. Click on any visible object with the mouse and hit the 'G' key to fly directly to it. Search for objects by name, search by parameters within a certain radius, browse an interactive map of the surrounding space and view a map of the current planetary system.
Save locations and name objects	Save a favorite point in space and time and share it with friend. Give a name to any discovered planet, star or galaxy, and write a description for it.
Observe the Universe in motion	Accelerate, decelerate, or reverse the flow of time to see the orbital motion of planets and moons, and watch sunsets and eclipses.
Tools to learn how the Universe works	Read detailed physical and astronomical data of any celestial body using the built-in Wiki system. Look at the orbital path lines of planets and moons, and compare their size side-by-side.
3D landscapes on planets	Volumetric galaxies and nebulae. Solar System bodies have real terrain models obtained by space probes; realistic hi-detail terrain on procedural planets.
Photorealistic graphics	Photorealistic lighting and atmospheric model.
Space ships with realistic orbital mechanics	Pilot star ships with realistic orbital mechanics, Alcubierre warp drives, and aerodynamics in planetary atmospheres.
Multilanguage interface	Localization in 20 languages, with a simple system for creating new translations.
Huge modding ability	Import space ship models, planetary surface textures and terrain, astronomical catalogs, and more.

And much more!
