Our Solar System

Space is full of interesting things like 8 planets, thousands of stars, 166 moons, a sun and galaxies. In space the is zero gravity. That means that you are floating all the time. In space it is also hard to breath because there are no trees and when there are no trees there that means there is no oxygen. Which planets have rings around them?


In our solar system there is 8 planets they are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. You are probably wondering why I haven’t put Pluto in, that is because Pluto is a dwarf planet. If you are a planet one of the things you have to be doing is orbiting around the sun by yourself but Pluto wasn't it had been orbiting around the sun with other planets. So that is why Pluto is now a dwarf planet.


In our galaxies there are thousands of stars. There is one star you probably know it, it is the sun. There are some stars that are 100 to 200 times bigger than the sun. In the sky there are thing called constellations. Constellation are groups of stars that make out shapes in the sky. Star are made out of dust and gas. They are formed by a gas and dust cloud. The clouds start to shrink and get smaller as the clouds get smaller they break up into clumps. After a while the clumps get hot and dense then the nuclear reaction starts and when the clump gets really really hot the clump turns into a star. A nuclear reaction is when gasses get really hot and dense and a nuclear reactions starts.


The moon and the sun orbit around the earth all the time. When the moon is on one side of the earth the sun is on the other side. There are 166 moons in our solar system. Earth has 1, Mars has 2, Jupiter has 63, Saturn has 60, Uranus has 27 and Neptune has 13. The sun is made out of helium and hydrogen.


The solar system is full of amazing things. Now to answer my question the planets    

have rings around them are Jupiter, Saturn, Uranus and Neptune. Rings are formed by rocks orbiting around the planets.
