A fun little gravity project that I made with html5 canvas and some ES6 javascript.
It was created through using Cowell's Method of orbital modeling simulation.
It has been slightly modified to not deal with numbers with factors of 10^20 or so. So, there is no gravitational constant involved and instead of the distances being cubed I went with the distance just being squared. Most of the modifications came out from just playing around with the method and seeing what looked good.
