If you're into gazing at the stars then you might find AstroGrav an excellent way to do so without even touching a telescope.
AstroGrav allows you to simulate how astronomical objects move and interact under the force of gravity. It features some impress interactive 3D graphics which allow you to move around within virtual astronomical system, while watching how it evolves with the passage of time.
There are a wide variety of sample environments included in the program such as Solar System, space mission, and abstract systems. These enable you to experiment with the software without having to enter any of your own data. However, if you are some kind of astronomical whizz, then you can also edit and create your own astrological environments. However, this is very complex and only for those that are either professional astronomers or have specialised knowledge of the solar system and how the coordinates of stars work.
For astronomers and space fans, AstroGrav is a fun and highly customisable astronomy program that's as enjoyable as it educational.
