Detailed explanation-1: -There is gravity everywhere. It gives shape to the orbits of the planets, the solar system, and even galaxies. Gravity from the Sun reaches throughout the solar system and beyond, keeping the planets in their orbits. Gravity from Earth keeps the Moon and human-made satellites in orbit.
Detailed explanation-2: -Gravity is the powerful force that glues our universe together. Gravity helped form our solar system, the planets, and the stars. It holds the planets in orbit around the Sun, and moons in orbit around the planets.
Detailed explanation-3: -What role did gravity play in the formation of the planets? Gravitational forces brought together several moon-sized bodies, called planetesimals, to form larger bodies that became planets.
