We’ve been having a fantastic time exploring the solar system together, and there’s still so much more to discover! So far, we’ve learned about the eight main planets: the four rocky ones and the four gas giants. We’ve also talked about smaller objects like asteroids and comets. But did you know there are also things called dwarf planets? They’re smaller than regular planets but bigger than asteroids.
Dwarf planets are a lot like regular planets. They are mostly round and travel around the sun. However, they are smaller, and their journey around the sun is a bit bumpier. This is because their paths are filled with other space objects like asteroids. Imagine the orbits around the sun as lanes on a highway. Regular planets have their own lanes, but dwarf planets share theirs with lots of other things.
So far, astronomers have named five dwarf planets. Most of them are far from Earth, in a cold area beyond Neptune called the Kuiper Belt. Let’s meet them!
Pluto is probably the most famous dwarf planet. It was once considered a regular planet until scientists found many other similar objects farther out in the solar system. Pluto is super interesting because it’s very cold, with temperatures dropping to 225 degrees below zero. Brrr!
Haumea spins really fast, making a day there only four hours long! Scientists think it might have collided with another object long ago, which could explain its fast spin and oval shape.
Discovered around Easter, Makemake was nicknamed the “Easter Bunny” by astronomers. It’s very cold and bright, with lots of shiny ice. Some chemicals on its surface make it look pink!
Eris is the biggest dwarf planet, even a bit larger than Pluto. It has its own tiny moon, too!
Ceres is the closest dwarf planet to the sun, located in the asteroid belt between Mars and Jupiter. It’s the smallest dwarf planet and is also considered a big asteroid. Ceres was the first dwarf planet visited by a spacecraft, which took amazing pictures and measurements.
Scientists believe there are many more dwarf planets to discover in our solar system. So, there will be lots more exciting worlds for us to explore in the future!
