AstroGrav is a software application that allows you to study how astronomical objects move and interact under the force of gravity.
AstroGrav 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.
AstroGrav is an astronomy software program that can be used for simulating the way astronomical objects shift and interact when affected by the force of gravity.Astro Grav 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.
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.
Here are some key features of "AstroGrav":
· Basic concepts of mass, position, velocity, acceleration, force, momentum, and energy.

· Many body systems and the n-body problem.
· Orbits and Lagrange points.
· Interchange of potential energy and kinetic energy in gravitational systems.
· Projectiles and escape velociti es.
· Gravitational slingshots used in space missions.
Requirements:
· 600 MHz Intel Pentium III processor or equivalent
· 128 MB RAM
· 50 MB disk space
· Java
Limitations:
· 14 days trial
· Nag screen
What's New in This Release: [ read full changelog ]
· Made many improvements to the display of ecliptic grids and equatorial grids.
· In solar system simulations, added ascending node indicators and descending node indicators to the orbits of selected objects that have the Sun as a parent.
· Improved the magnitude key by making the magnitudes of the key stars sensitive to the magnification and brightness.
· Made the crosses indicating selected objects visible regardless of whether or not the object itself is bright enough to be visible.
· Corrected a fault that caused AstroGrav to crash when viewing from the single object in a simulation with just one object.
· Made several improvements to the asteroid and comet tables that are displayed with the Edit / Import... command.
· Corrected a fault that could cause an edited orbital period to get corrupted when using the object editor.
· Added the Tau Ceti sample simulation in order to illustrate the system of five planets that have recently been found to be orbiting the star Tau Ceti.
· Various minor...
