🌍🌕 Why do some planets have moons?

Some planets have moons because they are like big space magnets! 🌌 When a planet is very big and strong, it can pull smaller rocks or balls of ice to stay close to it. These rocks or ice balls become moons! 🌕

For example, Earth has one moon, but Jupiter has 79 moons because it's much bigger!

Planets have moons because of gravity and how they formed in space! 🌠 When the solar system was young, there were lots of rocks and ice floating around. Big planets like Jupiter or Saturn pulled these rocks into orbit around them, and they became moons.

Some moons were even formed when big space rocks crashed into planets, and the pieces flew out and got trapped by gravity! 🌍💥

Earth's moon might have been made this way—a long time ago, a giant rock hit Earth, and the pieces came together to form our moon!

Moons are natural satellites that orbit planets due to gravitational forces. There are three main ways moons form:

1. Capture: Large planets like Jupiter can pull passing asteroids or comets into orbit, turning them into moons.
2. Collision: A massive impact (like the one that likely formed Earth's moon) can eject debris that later clumps together into a moon.
3. Accretion: Moons can form from the same swirling gas and dust that created their parent planet.

Gas giants (like Jupiter and Saturn) have many moons because their strong gravity captures more objects. Smaller planets like Mercury or Venus have few or none because their gravity is weaker.
