AstroGrav iconAstroGrav 2.2.3

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.
