A 2D gravity simulation I made on Unity Engine.

So it´s basically a simulation of n-body systems with certain mass that attract each other.
It´s all constructed using the Newton gravity equation F=G*m1*m2/r^2 and force equation F=m*a

Realtime drawn trajectories

Trajectories drawn having in mind the influence of mass, position, velocity and your personal gravitatory constant haha.

Relative point of view

Still working on this. You can choose one planet to center the camera and redraw the way the trajectories would be seen from that planet´s point of view.

Other cool stuff

So there´s a beautiful periodical solution to the popular 3-body problem.
Here it is.

Here it show how you would see those trajectories from one of the planets view.
