Made Gravity simulator in Unity

Added Roche limit calculation! Accurate to the ~4 km (Only tested on Mars and it's Moon,Phobos).It's basically the point where body's fragment (dependingonMass) due to tidal forces. Sadly, I have encountered an issue with it going straight towards Mars when it should go into orbit when adding horizontal force (Which I do but still happens). If anyone knows C# here's the code https://hastebin.com/ohagotenel.cs(Unity). Hoping to fix it sometime!
