3. Venus has winds blowing at speeds of **224 mph**, faster than its rotation.
4. Earth’s magnetic field is constantly deflecting charged particles from the Sun, creating the **Aurora Borealis and Australis**.
5. The Moon is slowly drifting away from Earth by about **1.5 inches per year**.
6. Mars has the largest dust storms in the solar system, sometimes engulfing the entire planet for weeks.
7. Jupiter emits more heat than it receives from the Sun due to its gravitational compression.
8. Saturn’s rings are made mostly of **water ice**, some particles as small as dust and others as big as mountains.
9. Uranus rotates on its side, likely due to a massive collision billions of years ago.
10. Neptune’s winds are the fastest in the solar system, reaching speeds of **1,200 mph**.
