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.


Cosmographia is described as '"NAIF offers for public use a SPICE-enhanced version of the visualization tool Cosmographia. This is an interactive tool used to produce 3D visualizations of planet ephemerides, sizes and shapes; spacecraft trajectories and orientations; and instrument field-of-views and' and is an app in the education & reference category. There are nine alternatives to Cosmographia for a variety of platforms, including Windows, Linux, Mac, iPad and Web-based apps. The best Cosmographia alternative is Stellarium, which is both free and Open Source. Other great apps like Cosmographia are Celestia, Space Engine, Universe Sandbox and Noctua Stellarium.

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.



Space Engine - a real-time 3D space simulator, procedural universe generator and visualiser. It lets you explore the universe in three dimensions, starting from planet Earth to the most distant galaxies.



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.






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




Gravity and space simulator that allows you to learn about the gravitational force and explore and learn about space. Change the value of the gravitational constant, increase the mass of Jupiter to see how doing so would affect the solar system and much, much more!
Systems Tool Kit (STK) is a platform for analyzing and visualizing complex systems in the context of your mission. Interact with data from platforms across the aerospace, defense, telecommunications, and other industries.
