AstroGrav 3.0

Planets and asteroids movement and interaction simulator for your Mac
AstroGrav is a cross-platform (Mac OS X and Windows) astronomy app that helps you to simulate how astronomical objects interact and move under the force of gravity.

Moreover, AstroGrav comes with stunning looking interactive 3D graphics which enable you to move around within a many-body astronomical system, while also being able to watch how it evolves with the passage of time.

Furthermore, a large variety of sample files are provided, including space mission, Solar System, and abstract systems, these enabling you to experiment with Astrograv without having to enter your own data.

AstroGrav's comprehensive editing facilities will allow you to either create your own astronomical systems, or to modify existing ones, thus providing you with an almost endless scope for investigation and experimentation.

As an added advantage, the AstroGrav app calculates how astronomical objects move according to Newton's Law of Gravitation, and displays the results as they are calculated so that you can watch the system evolve as in a movie.

In addition, AstroGrav is very accurate, dynamically calculates orbits as a system evolves, deals correctly with object collisions, and can cope simultaneously with objects on many different timescales.

Main features:

  • Astronomers interested in the evolution of gravitational systems.
  • Educationalists seeking to deliver programs on math, physics, or astronomy.
  • Students of math, physics, or astronomy.
  • Anyone else interested in studying how objects move and interact under the force of gravity.

What's New in This Release:
  • VIEW WINDOW IMPROVEMENTS:
  • 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.
