About AstroGrav
A program that allows you to study how astronomical objects move and interact under the force of gravity. It features superb interactive 3D graphics which allow you to move around within an astronomical system that you are viewing, while watching how it evolves with the passage of time.

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. 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.

What’s New in this Version
- Added a facility to save and restore family patterns in the ‘Edit/New Family…’ command.
- Added the ‘Comet Gehrels 3’ and ‘Disaster!’ sample simulations.
- Corrected a fault that caused a very slow response to an attempt to select a large number of objects.
- The keyboard shortcut for the ‘Evolve/Run Backward’ command now works correctly.
- Expanding and collapsing a tree node can now only be done by using its handle, and not by double-clicking on it.
- Corrected a fault that caused the preference for opening the root node of trees to be ignored in some cases.
- Various minor bug fixes and improvements.
