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.



3D visualization software for ESA's (European Space Agency) Gaia mission to chart about 1 billion stars of the Milky Way Galaxy.




Universe Sandbox is an interactive space simulator for Windows based PCs.
Unlike most astronomy software that just shows you what the sky looks like or where the planets are, Universe Sandbox is a powerful gravity simulator. You can add another star to our solar system and watch.






3D simulation of the Solar System and night sky - real time virtual orrery and observatory




Planetario contains a 3D model of our solar system. It will show the horizon and the planets in their path along the sky. The word planet comes from the Greek planetai, meaning "wanderers". Because of the rotation of the earth, the stars seem to move in perfect...




Welcome to the Atlas of Space — an interactive visualization to explore the planets, moons, asteroids, and other objects in the Solar System.


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.


Aciqra (uh-SEE-kruh) is a free and open source virtual sky map and planetarium which tracks and displays astronomical bodies including planets, nebulae and stars to an accuracy of a fraction of a degree for thousands of years into both the future and the past.


A browser-based virtual planetarium of stars and planets customizable by location (latitude and longitude) and time of day.

SourceForge presents the Solar Model project. Solar Model is an open source application. SourceForge provides the world's largest selection of Open Source Software. The Solar Model is real time modeling of solar system.
