ELI5: Explain Like I'm 5

Kepler orbit

Kepler's orbit is like a shape that a planet or other object makes when it goes around a star. It looks like a cone or an oval with two round edges (like an egg). It's never perfectly round, but each planet in our Solar System follows a path like this. The farther a planet is from the star, the bigger the orbit and the longer it takes to go around the star. Kepler's orbit helps us understand how the planets in our Solar System move.
