Celestia is described as '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' and is a very popular Star Map in the education & reference category. There are more than 25 alternatives to Celestia for a variety of platforms, including Windows, Mac, Linux, Android and iPad apps. The best Celestia alternative is Stellarium, which is both free and Open Source. Other great apps like Celestia are Space Engine, Universe Sandbox, Solar System Scope and Noctua Stellarium.
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.
