WinStars is described as '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' and is a Star Map in the education & reference category. There are more than 10 alternatives to WinStars for a variety of platforms, including Windows, Linux, Web-based, Android and Mac apps. The best WinStars alternative is Google Earth.
