The Sun and Our Solar System

- The sun are the greatest of all the planet in our solar system

The Solar Systems centre is a big star that we call the sun. All planets in our solar system circles around it include our planet the earth. With out the sun there wouldn’t be any kind of life on our earth. The temperature on the surface on the can be about 6000 degrease, but the something very amazing is that I the middle of the sun the temperature can get up to 15 millions degrease.

The sun is with out compare the biggest object in our solar system. It contains about 99,8 % of the gathered weight of the all the planets in our solar system. (Jupiter contains almost the rest of what’s left)

Right now the sun exists of 75 % hydrogen and 25 % helium. There are more substances but they only count for about 0,1 %. But the balance of these masses is changing, but it isn’t very big changes that happens to be.

The outer layer of the sun is fluid, so that means that if you stand with equator it will take you 25,5 days to rotate a hole round. But if you are standing near the poles it will take you 36 days. This strange thing cause that the sun isn’t a firm object like the earth.
