☀ The eight planets

Unit 1 · Our cosmic neighbourhood · 9 min

Our solar system has eight planets, nearest to farthest: Mercury, Venus, Earth, Mars (rocky), Jupiter, Saturn (gas giants), Uranus, Neptune (ice giants). Jupiter is the biggest; Venus is the hottest because its thick CO₂ atmosphere traps heat.
