AstroGrav Astronomy Software 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. View Movies : Download AstroGrav 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 To find a range of illustrative movies, click on the movies item in the menu bar on the left. Multi-Purpose Because it calculates the motions of bodies from their gravitational interactions, AstroGrav is not restricted to just the solar system. Any situation in which gravity is the only significant force can be simulated, and the illustrative sample files that are included with AstroGrav include many examples. Systems that can be simulated include: Exoplanet systems

Protoplanets that evolve into planetary systems

Rubble piles and their interactions with massive bodies

Complex star systems, including colliding globular clusters

Projectiles and bouncing balls Educational The AstroGrav software also has a great educational potential, and so site licenses are available for educational institutions. AstroGrav can be used to visualize and understand many aspects of physical, gravitational, and astronomical systems including: Basic concepts of mass, position, velocity, acceleration, force, momentum, and energy

Kepler's Laws of Planetary Motion and Newton's Universal Law of Gravitation

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 velocities

Gravitational slingshots used in space missions AstroGrav Users AstroGrav is ideal for any of the following: Astronomers, astrophysicists, and researchers interested in studying the evolution of gravitational systems

Teachers and educationalists seeking to deliver courses on math, physics, astronomy, or astrophysics

Students of math, physics, astronomy, or astrophysics
