Kepler’s second law is about how planets move around the Sun, and it’s like going on a bike ride where you speed up and slow down depending on the path.
Imagine you're riding your bike in a circular track, but sometimes the path gets closer to the center (like when you're near the start line) and sometimes farther away (like when you're near the finish line). When you’re closer to the center, you go faster, just like when you pedal harder. When you’re farther out, you go slower, like when you take a break.
This is exactly what happens with planets! A planet moves faster when it’s close to the Sun and slower when it's far away. It’s like a dance, the planet speeds up as it zooms toward the Sun, then slows down as it drifts away again.
Why does this happen?
Think of it like pulling a rope around a pole. When you’re near the pole (the Sun), you have to move more quickly to keep going in a circle. But when you're farther out, you can take your time, it's like having a longer rope to swing around.
So Kepler’s second law shows us that planets don’t move at a constant speed, they race toward the Sun and sail away from it, just like you on your bike!

Examples
- Imagine running around a track, you sprint on the inside lane and slow down on the outside.
- If Earth were in an oval-shaped orbit instead of circular, we'd speed up as we neared the sun.
