The sun is the heaviest object in the solar system and exerts the strongest gravitational force. Thus, the sun is characterized by a strong gravitational force around it. The sun’s gravitational force is responsible for ensuring that the planets orbit the sun. The motion of the smaller objects in the solar system creates a sideways force that keeps them from falling in the sun. These forces ensure that the planets orbit the sun in paths known as ellipses. Objects with more mass exert stronger gravitational forces on objects with less mass. The concept explains the planet’s motion around the sun and the motion of the moon and other smaller objects around the planets. Sir Isaac Newton is recognized and credited with the discovery and explanation of gravitational forces on objects.
