Our Solar System

The Sun and everything gravitationally bound to it — 8 planets, dwarf planets, moons, asteroids, and comets.

PERSONAL FIELD NOTE

💡 Analogies

The solar system is like a vast skating rink — the Sun is the bright light in the center, and the planets are skaters circling around it at different speeds and distances.

⚠️ Common Misconceptions

✗

Myth: The planets are close together like in diagrams.

✓

Reality: Space is mostly empty! If Earth were a peppercorn, Jupiter would be a chestnut 550 meters away, and Neptune would be 2.3 km away. Diagrams wildly compress the distances.
