AstroGrav 3.0

User friendly astronomy application for Mac OS X that can simulate the movement of planets and asteroids, and allows you to observe the interaction of different objects.
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.

Easy to use astronomy software solution that simulates the solar system

To help you get started, AstroGrav comes with a collection of sample simulations covering different subjects: abstract systems, the exoplanet systems, the solar system, or space missions. Within the AstroGrav’s main window, you will be able to preview the simulations, and analyze the data.

Of course, you will also be able to create your own simulations by defining new objects in the Table window: after editing the appropriate parameters, simply open a New View window in order to run the simulation and visualize the effects.

Run experiments involving astronomical bodies in a solar system simulator

The application comes with extensive details about the solar system, including more than 100.000 background stars. At the same time, it provides support for different coordinate grids and allows you to visualize the objects from any Earth location, in planetarium view mode.

However, 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.

Powerful simulation tool that can help you run tests using the solar system as your environment

AstroGrav offers you the possibility to visualize the celestial bodies in planetarium style, while running various simulations involving user defined objects. Since the app is able to calculate both the trajectories and interactions, you will be able to see how the solar system evolves in time, taking into consideration your modifications.

What's New in This Release:
  • In solar system simulations, it is now possible to view from points on the Earth's surface, instead of only being able to view from its center. When you use Alt+Control+Click (Alt+Command+Click on a Mac) on the Earth, you now get a location chooser displayed that allows you to choose a location on the Earth's surface. A list of locations is supplied with AstroGrav, and this contains well over 100 of the world's best known cities, as well as the center of the Earth so that you can still view from the Earth's center if you wish. This list of locations can be edited with the new Edit / Locations... command, so that you can easily add your own location, together with any other locations that are of interest to you.
  • When you use Alt+Shift+Click on an object that is already fixed, the fixed point changes to the barycenter of the object's family. Repeatedly using Alt+Shift+Click on an object switches between fixing the object itself and fixing the barycenter of the object's family.
  • The View/Background/Horizontal Grid menu item and tool have been added. This shows the local horizontal (altitude-azimuth) coordinate grid at the point on the Earth's surface that you are viewing from. This command is only available when you are viewing from somewhere on the Earth's surface in solar system simulations.
