Imagine Earth like a child on a swing, going around the Sun. Now, if another planet, like Mars, suddenly took its place, Earth would be flung out of its usual path. Like when someone jumps in front of you on a swing, you go flying! This might make Earth colder or warmer, and it could change how life grows here.
Examples
- Imagine Earth being flung out of its path by a big planet like Jupiter passing nearby.
- If another planet stole our orbit, the Sun would look smaller in the sky.
