Everything that has weight has gravity, but bigger things have more. Earth is very big, so it has strong gravity that holds us, the oceans, and even the air in place. The Sun’s gravity is even stronger, and it keeps all the planets going around it. The Moon’s gravity pulls on Earth’s oceans and creates the tides!
- You weigh less on the Moon because it has weaker gravity than Earth.
- If you could stand on Jupiter, you would feel super heavy because Jupiter’s gravity is much stronger.
- A famous scientist named Isaac Newton figured out how gravity works after watching an apple fall from a tree!
