is where the planet moves on it line which is called an orbit

Explanation:

Abstract

In this part of the book we describe the rotation of planets and moons of the solar system. Besides providing information on the current rotation rate and orientation of these bodies, we discuss the changes in the rotation speed and orientation on both short and long timescales. We show how information on the planetary interior and dynamics can be determined from observations of changes in rotation and orientation and what we have learned so far.

I hope it's helpful!!
