What Limits Exist?

Why don’t planets just fall into the sun? One reason is gravity, the force that pulls planets toward the sun. Another reason is the speed at which planets are moving around the sun. A third factor is the balance between these forces, which keeps planets in a stable orbit instead of crashing into the sun. This balance is crucial—it’s like a game of tug-of-war that’s always evenly matched.

🧠 Pause & Think: What do you think would happen if a planet slowed down too much?

⚖️ Choose: Would you pick: A. Stronger gravity which keeps things more stable B. Faster movement to explore more places Why?
