AstroGrav 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.
The AstroGrav software has a huge range of features and viewing options, including views from space or any object, planetarium-style views from any location on Earth, multiple views animated simultaneously, dynamically calculated orbits and trajectories, comprehensive tabular data, and simulation time steps from a fraction of a second to thousands of years. Constellations and over 100,000 background stars are included, with comprehensive data for every star. Several different celestial coordinate grids and a wide range of physical units are available, and editing facilities allow you to create new objects manually, or import from hundreds of thousands of asteroids and comets.
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 such as exoplanet systems, protoplanets that evolve into planetary systems, rubble piles and their interactions with massive bodies, complex star systems, and even projectiles and bouncing balls.
AstroGrav is ideal for astronomers, astrophysicists, researchers, teachers, educationalists, and students, and comes complete with a tutorial and full documentation. A fully functional 15 day trial version is available for download and evaluation.

AstroGrav 4.3.1 is now available for download. The most significant change is a fix for a bug in version 4.3 that was causing poor display quality on some high resolution screens. There is also a fix for a bug that could cause some of the information to be missing from view window popups. 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 AstroGrav videos show a range of astronomical and gravity simulations that have been created with the AstroGrav software. Installation To install AstroGrav, double-click on AstroGravInstall.exe to open the installer, and then follow the on-screen instructions.

Editing Objects
The new object editor is smaller, easier to understand, and easier to use, with the units of fields changed from labels to popup menus so that units can now be adjusted while editing fields. The absolute magnitude of an asteroid or comet can be specified in a solar system simulation, with this being used to automatically calculate an appropriate mass and radius. Other fields that have been added include pericenter distance, descending node, and pericenter / perihelion time. There's also the choice a choice of reference frames to use when adding an object in orbit around the Earth, which is very useful when adding artificial satellites to a simulation. Finally, there's also the opportunity to specify the epoch at which a new object is to be added.
Other ImprovementsA 'Lowell Asteroids' option has been added to the object importer, which gives access to about 1,000,000 asteroids in the Lowell Asteroid Orbital Elements Database. There are several improvements to the accuracy of simulation evolution, with the handling of general relativity being much improved, and the oblateness of solar system planets being taken into consideration, which dramatically improves the accuracy of the simulation of the major planets' inner moons. There are improvements to ephemeris generation, and a new 'Barycentric Dynamical Time' (TDB) unit has been added to the date units. 'Light-Time Correction' labels have been changed to 'Planetary Aberration' labels to reflect the fact that stellar aberration and diurnal aberration are taken into account in addition to light-time correction. Background stars are now adjusted for stellar aberration and diurnal aberration - something that was missing from earlier versions, resulting in errors in positions of up to 21 arcseconds. Many other improvements and bug fixes complete this major upgrade.
