Is this magic?

The Radius of an Orbit found from the Radius of the Orbiter.

This only applies to orbiters having axial rotation.

An experiment:

A bicycle with wheels of 10″ radius cycles round a velodrome and completes the course in 740 turns.

This makes the radius of the velodrome track 10″ x 740 = 7400″ (or 616.6 feet).

This can be verified by finding the circumference of the bicycle wheel by: 10″ x 2 = 20″ (diameter) x 3.14 (PI).

This is 62.8 inches

Multiply the number of turns it took to complete a circuit by this length.

740 x 62.8″ – 46,472″. This is the length of the circuit.

Divide this by 3.14 (PI) = 14800″ (diameter) ÷ 2 (for radius) = 7400″ radius.

You can try this with any size of circumference or any size of orbiter. The radius of the circle will always be the same as the radius of the orbiter, multiplied by the number of cycles.
