Transcript of The Sun
The Sun is a huge, glowing sphere of hot gas. Most of this gas is Hydrogen about 70% and Helium is about 28%. Carbon, Nitrogen and Oxygen make up to 1.5% And the other 0.5% is made up of small amounts of many other elements such as Neon, Iron, Silicon, Magnesium and Sulphur.
This is what it is made of.
Where is the Sun?
The Sun is in the center of the Solar System. Every planet in the Solar System orbits around the Sun.
What will happen to the Sun in the future?
In the future, the Sun will get so big and be so hot that you cannot walk outside on Earth. The Sun may get so big that it will cover the Universe and destroy EVERYTHING.
Was the Sun the first star or planet in the Solar System?
The Sun was not the first star or planet in the Solar System.
Similarities & Differences
Facts About The Sun
Why Do Planets Go Around the Sun?
By Nikita,Dan,Joshua and Thomas.
The Sun is in the middle of the solar system.
What Is It Made Of?
The first thing in the Solar System was bits of rocks and dust.
Rocks and dust.
The most important difference between our Sun and other stars is that the Sun is closer to Earth than any other star. The other possible differences are mass, size, temperature, and age.
Most stars, about nine out of ten, are less massive than the Sun. The smallest are only about three times as big as Earth. About one out of ten stars are similar in mass to our Sun.
The Sun is a pretty small star as compared with the giants in the Universe. Only about one out of one hundred stars are more than eight times as massive as our Sun. The largest star, Mu Cephei is so large you could fit over one billion of our Suns inside of it!

Type Of Star: Yellow Dwarf
Diameter: 1,392,684 km
Circumference at Equator: 4,370,005.6 km
Mass: 1,989,100,000,000,000,000,000 Billion kg (333,060 x Earth)
Surface Temperature: 5500 °C
When all the Hydrogen has been burned, the Sun will continue for about 130 million more years, burning Helium, during which time it will expand to the point that it will engulf Mercury, Venus and the Earth. At this stage it will have become a RED GIANT.
The Sun pulls the planets in with it's gravity but it is not enough to pull the planets in.
