The Sun and the eight planets
The solar system is the Sun and everything that orbits it, including the eight planets. Here is what happens at each labeled part of the diagram:
| Object | What it does |
|---|---|
| Sun | The star at the center of the solar system; its gravity holds everything in orbit. |
| Mercury | The smallest planet and the closest to the Sun. |
| Venus | The hottest planet, wrapped in thick, cloudy air. |
| Earth | Our home — the only planet known to have life and liquid water. |
| Mars | The red planet, named for its rusty, iron-rich soil. |
| Jupiter | The largest planet, a giant ball of gas with a Great Red Spot. |
| Saturn | The ringed planet, famous for its bright rings of ice and rock. |
| Uranus | An ice giant that spins on its side. |
| Neptune | The farthest planet from the Sun — a cold, windy ice giant. |
