The Solar System is the Sun and everything that moves around it.
The Sun is a star at the centre. Eight planets orbit (go around) the Sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Earth is the third planet from the Sun and the one we live on.
Remember
- The Sun is a star at the centre; 8 planets orbit it.
- Earth is the 3rd planet from the Sun.
