AstroGrav 5.3

AstroGrav for Windows and Mac is a full-featured, high precision solar system simulator that calculates the gravitational interactions between all astronomical bodies, so that the motions of asteroids and comets are simulated much more accurately than with planetarium applications. The effects of general relativity and radiation pressure can be taken into account, and superb interactive 3D viewing allows you to easily rotate and zoom your view while the solar system evolves.

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 tracks
• 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
