A program that permits you to study how astronomical objects move and interact under the force of gravity

A wide variety of sample files are provided, including Solar System, space mission, and abstract systems, and these enable you to experiment with AstroGrav without having to go to the trouble of entering your own data.

AstroGrav calculates how the various objects move corresponding to Newton's Universal Law of Gravitation, and displays the results as they are calculated. AstroGrav is very accurate, dynamically calculates orbits as a system evolves, deals correctly with object collisions, and can cope simultaneously with objects on many different timescales.

AstroGrav is a software application that permits you to study how astronomical objects move and interact under the force of gravity.

AstroGrav features superb interactive 3D graphics that allow you to move around within an astronomical system that you are viewing, while watching how it evolves with the passage of time.

The comprehensive editing facilities allow you to either create your own astronomical systems, or to modify existing ones, and provide you with an almost endless scope for experimentation and investigation.

For a system containing a small number of particles, you can watch the system evolve as in a movie. For a system containing a larger number of particles, the calculations will take longer, and you may have to wait to see the next state of the system.
