Skyhook

A skyhook is a theoretical machine that would assist in accelerating a spacecraft away from a planet. It works by rotating around it's axis while also revolving around a planet. This is a demonstration of the path the scoop  (the end of the skyhook that a ship can attach to) would take showing how it's motion relative to the planet slows, allowing a ship to attach and be catapulted into space. 

I designed this in Unity because I wanted a visual understand of how the object would be accelerated.
