This is considered today to be an impossible task; to calculate exactly what generates spin in stars, planets and moons.
It is the energy developed in a satellite from its force-centre and secondary satellites that causes a satellite to spin.
Isaac Newton’s laws of motion provide all the information needed to calculate this energy, if you only know where to look. This calculator tells you where to look and how to apply it. Spin‘s output data is as exact as Newton’s laws of motion themselves.
Spin uses the appropriate results from CalQlata’s Newton calculator to determine a satellite's (e.g. the earth) spin energy and angular velocity (incl. direction) or its delta value, which is used to define its polar moment of inertia.

Spin calculates the angular velocity and direction in satellites.
