Key Takeaways
- Jupiter is the largest planet, while Mercury is the smallest.
- Saturn currently holds the record for the most satellites (146).
- Mercury and Venus are the only planets in our solar system without any moons.
- Neptune has the longest orbital period, taking about 165 Earth years to orbit the Sun.
What to Avoid
- Do not confuse the order of planets by distance with their order by size (e.g., Earth is 3rd by distance but 5th by size).
- Do not mistake the inner planets (rocky) for the outer planets (gas giants).
- Avoid using outdated satellite counts; Saturn is currently recognized with 146 satellites.
