Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope.


Space Engine is not available for Linux but there are some alternatives that runs on Linux with similar functionality. The best Linux alternative is Stellarium, which is both free and Open Source. If that doesn't suit you, our users have ranked more than 25 alternatives to Space Engine and seven of them are available for Linux so hopefully you can find a suitable replacement. Other interesting Linux alternatives to Space Engine are Celestia, Universe Sandbox, Gaia Sky and WinStars.

Celestia is an application for real-time 3D visualization of space, with a detailed model of the solar system, over 100,000 stars, more than 10,000 galaxies, and an extension mechanism for adding more objects.



Create & destroy on an unimaginable scale with a realistic physics-based space simulator. Explore the beauty of our universe and the fragility of our planet. Use science to bend the laws of gravity, collide planets, boil away oceans, fire epic space lasers, and customize your universe.


WinStars uses the latest 3D technology to show the objects of our solar system in a realistic manner. Thus, it is possible to move from one planet to another, to follow a space probe on its long voyage or to observe a celestial event from a place to which you could never go.


OpenSpace is open-source interactive data visualization software designed to visualize the entire known universe and portray our ongoing efforts to investigate the cosmos.




I want to explore other Earth-like planets and it only seems to let you look at the night sky.
