Bodies of comparable masses orbit about their common center of mass and their velocities and periods should be determined from Newton’s second law and law of gravitation.

Gravitation is a fundamental force of nature that governs the motion of objects throughout the universe. It is the attractive force that draws two bodies toward one another, resulting in a pull that depends on …
