👉 Epicyesis, also known as the "parasitic limb", is a concept in physics that describes how an object's motion can be described by considering its motion relative to another object or system. This means that if two objects are moving towards each other at constant speeds, their combined motion will be considered as being parallel to the initial velocity of one of them. In the context of epicycles, a "parasitic limb" is an imaginary line connecting an object's center of mass
