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
- Improved the way that evolution is indicated on the status line.
- Corrected a fault that occasionally caused part of an orbit to be drawn as a straight line instead of as a curve.
- Corrected a fault that caused the magnitudes of objects to be displayed incorrectly.
- Significantly speeded up the drawing of model windows.
- Corrected a bug that sometimes caused a non-luminous object (such as a planet) to be invisible when in transit against a luminous object (such as the Sun).
- Various minor bug fixes and improvements.
