AstroGrav is a solar system simulator that offers you the possibility to run different scenarios in order to understand how different astronomical objects interact with each other. The environment emulates the solar system with precision, which leads to accurate results for your simulations. AstroGrav is also able to calculate the trajectories, orbits, or gravitational interactions of various user defined objects. You have the option to edit over 30 different parameters and take simulations steps that vary from thousands of years to a single second. As a result, you can easily run your own tests and monitor how the solar system evolves in time.

Features
The AstroGrav software has a huge range of features and viewing options including:

Views from space or any object, with planetarium-style views from any location on Earth
Multiple views animated simultaneously, with dynamically calculated orbits and trajectories
Comprehensive tabular data with over 30 editable fields available for each object
Simulation time steps from a fraction of a second to thousands of years
Constellations and over 100,000 background stars from the Hipparcos catalogue, with comprehensive data for every star
Tens of millions of additional background stars available as a separate download
Celestial coordinate grids: ecliptic, equatorial, galactic, and horizontal
A wide range of physical units, including astronomical, metric, and imperial
Editing facilities that allow you to create new objects manually, or import from a database of hundreds of thousands of asteroids and comets
A wide variety of illustrative sample files that can be used as they are, or used as the basis for your own simulations
