Detailed explanation-1: -The gravity of the sun keeps all the planets in orbit in our solar system.
Detailed explanation-2: -All in all, gravity runs the gamut here in the solar system, ranging from 0.38 g on Mercury and Mars to a powerful 2.528 g atop Jupiter’s clouds. And on the Moon, were astronauts have ventured, it is a very mild 0.1654 g, which allowed from some fun experiments in near-weightlessness!
Detailed explanation-3: -Gravity causes the motions of planets, stars, and galaxies. It’s why the Moon orbits around the Earth, and the Earth orbits around the Sun, and the solar system orbits around the galaxy. It’s all because of gravity.
Detailed explanation-4: -When two celestial bodies of comparable mass interact gravitationally, both orbit about a fixed point (the centre of mass of the two bodies). This point lies between the bodies on the line joining them at a position such that the products of the distance to each body with the mass of each body are equal.
