What is Earth’s elliptical orbit?

Earth’s elliptical orbit is like when you swing around on a rope, sometimes you’re close to the center, and sometimes you’re far away.

Imagine Earth as a kid swinging on a rope tied to a tree. The tree is like the Sun. When the kid swings closest to the tree, that's like Earth being closest to the Sun. When the kid swings farthest from the tree, that’s like Earth being farthest from the Sun. This path the kid takes, going close and then far, is called an ellipse, which means it's shaped more like an oval than a perfect circle.

Earth doesn’t go around the Sun in a perfect circle, but in an oval shape. That’s why sometimes we have warmer days (when Earth is closer) and colder days (when Earth is farther). It’s not because of magic, it's just how Earth moves!

Sometimes people think Earth is always the same distance from the Sun, but it's actually like walking around a slightly stretched-out circle, that’s what makes our elliptical orbit so special.
