Detailed explanation-1: -Rotation describes the circular motion of an object around its center. There are different ways things can rotate. A very familiar kind of rotation is when a spherical, three-dimensional object turns around an invisible line inside its center. This center is called an axis .
Detailed explanation-2: -A rotation around a completely external axis, e.g. the planet Earth around the Sun, is called revolving or orbiting, typically when it is produced by gravity, and the ends of the rotation axis can be called the orbital poles.
Detailed explanation-3: -When an object turns around an internal axis (like the Earth turns around its axis) it is called a rotation. When an object circles an external axis (like the Earth circles the sun) it is called a revolution. Let’s talk about rotation and revolution.
