🌍 Gravity

Gravity is an invisible pull that draws things toward each other, and the bigger something is, the stronger it pulls. The Earth is huge, so its gravity holds you, the oceans and the air firmly on the ground instead of letting them drift away.

The Earth's gravity is always pulling us toward its centre, which keeps our feet on the ground no matter where we stand on the planet. Even people on the far side of the world are pulled "down" toward the middle, so nobody falls off.

The Earth's gravity reaches all the way out to the Moon and keeps pulling it close. The Moon is also moving sideways very fast, so instead of falling into us or flying off, it keeps circling around the Earth in a steady loop.

The Sun is so enormous that its gravity reaches across the whole solar system and pulls every planet toward it. Each planet is also racing sideways, so it keeps swinging around the Sun in a giant loop instead of falling straight in.
