How do the planets and stars stay up in the sky?

Researchers were – M.J. & J.S.

We found out ……………..

Gravity is a force that pulls things together and holds them in place. We cannot see the force of gravity but it is happening all around us. Everything has gravity but some things have more gravity than others. Earth’s gravity holds things on Earth in place and gives them weight. In our Solar System the Sun is the biggest thing and because it is so big it’s force of gravity is really strong. So it is the Sun’s strong gravity that attracts the planets and keeps them up in space and holds our solar system together. Space is really big and our Solar System is a really tiny part of it. Some planets in our Solar System have a moon or moons around them and it is the force of gravity of the planet that they are going around that keeps them in orbit.
