WorldWide Telescope is described as 'The WorldWide Telescope (WWT) is a Web 2.0 visualization software environment that enables your computer to function as a virtual telescope, bringing together imagery from the best ground and space-based telescopes in the world for a seamless exploration of the universe' and is an app. There are more than 10 alternatives to WorldWide Telescope for a variety of platforms, including Windows, Linux, Mac, Web-based and Android apps. The best WorldWide Telescope alternative is Google Earth. It's not free, so if you're looking for a free alternative, you could try Google Earth or Stellarium. Other great apps like WorldWide Telescope are KStars, Gaia Sky, Solar System Scope and Noctua Stellarium.
Explore Earth from space to sea with detailed satellite imagery, 3D buildings, and ad-free service. Save toured places, share them, and explore offline all points of interest around the globe.
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.
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.
Open-source astronomy software offering accurate night sky simulation with 100 million stars, Ekos astrophotography suite, stellar observation planner, "What's up Tonight" tool, FOV editor, and a variety of celestial catalogs for comprehensive astronomical exploration.

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.
StarCalc is the fastest professional astronomy planetarium & star mapping program for Windows 9x/ME/NT/2000/XP (StarCalc version for PocketPC is available). It illustrates star positions of any instance of the day observed from any geographic locations on the Earth.
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.
