Dwarf planets are planets with a maximum of 500 km and an unclear orbit. There are four in our solar system, Pluto, Makemake, Eris and Ceres. Ceres is in the Asteroid belt and the rest are in the Oort cloud or the Keiper belt.

Dwarf planets
First, thank you for three hundred page views, i never thought I'd be here, I know its not much but it means a lot to me. Anyway, without further ado, lets begin!

Neptune
The final planet in the system. It has 13 moons and quite big rings. One of neptune's moons, titan, will crash into neptune and make rings for saturn to contend with. It takes 164 years to travel round the sun and it has an atmosphere of methane, hydrogen and helium. One day on neptune is 16 hours.
Well thats it, bye!

Saturn
Saturn is the sixth and second largest planet in our solar system. Its atmosphere is made up of methane and its rings of rock and ice. Saturn is well known for its rings of rocks and ice. The rocks scale up to 2 km to a speck of dust! It also has auroras. Saturn can have winds up to 300 mph. It has 60 moons.
Uranus
Ok, get the laughter out of you! Uranus is a gas giant with rings. It's axis is the opposite to Earths and it has 27 moons. Its atmosphere is made up of hydrogen, helium and methane. It takes roughly 17 hours to have one day and takes 84 years to orbit the sun.

Jupiter
The 5th planet in the solar system and the first gas giant, it is also the biggest planet. The majority of its atmosphere is made up of methane. It has had a storm in it for 300 year, you may know this as the red spot!
It has very thin rings from moons that has been smashed apart. A surprising fact about Jupiter is that it took only 10,000 years to form, which is very fast in astronomical terms.
Jupiter is like a body guard for Earth, as it smashes meteorites, that would otherwise hit Earth. Without Jupiter, we would possibly be dead by now. Another fact is that Jupiter has 63 moons and its gravitational field stretches over to Saturn!
Well guys that's it, see you!
