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.


Comments about Stellarium as an Alternative to Space Engine
Not an alternative. Stellarium is a planetarium application.
These don't do the same thing, Stellarium simulates the real sky as seen from Earth, Space Engine simulates interstellar travel, including real but also procedurally generated bodies.


- Stellarium is Free and Open Source





























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