Hey kiddo! Have you ever heard of a dwarf planet? No? Ok, let me explain it to you in a way that you can understand.
You know that we have a lot of planets in our solar system, right? But not all of them are the same size or have the same features. Some planets are huge, like Jupiter, while others are smaller like Mars. But there are some small worlds in our solar system that are not quite planets, and these are called dwarf planets.
Dwarf planets are like the little brothers or sisters of the major planets in our solar system. They are very small worlds that orbit the sun, just like other planets. However, there are some differences between dwarf planets and regular planets.
One of the main differences is their size. Dwarf planets are much smaller than regular planets, and they don't have the same gravitational pull as the bigger planets. This means that they don't have the power to clear their orbit of debris like other planets do, so they often have nearby objects around them (like asteroids, moons, and other small rocks).
Another difference is that dwarf planets have a different shape than planets. Planets are usually round and have a definite shape because of their strong gravity. But dwarf planets are irregularly shaped and look like big rocks.
Nowadays, astronomers have discovered five formally recognized dwarf planets in our solar system- Ceres, Pluto, Haumea, Makemake, and Eris. They all have some similarities and differences, but they all follow the rules that make them dwarf planets.
So, that's a little bit about what a dwarf planet is, bud. I hope that you understand it now!
