Once upon a time, in the ancient times, people believed that comets and asteroids were mythical creatures sent from the gods to bring either good or bad luck. But as time passed, people started to compare these objects with the other bodies in our solar system and realized they followed predictable orbits around the sun. They learned about our solar system being just a tiny part of the vast universe. The end.

Reflections

1. What did ancient people believe about comets and asteroids?
2. How did people's understanding of comets and asteroids change over time?
3. Why do comets and asteroids follow predictable orbits in our solar system?
4. What is the significance of our solar system being part of the universe?
