1 How Do Stars Effect The Earth By Joshua Wallace

2 What Is A Star? A star is a big ball of gas that is held together by gravity and force. They are formed when two clouds of dust meet. Interesting Fact: The Sun Is Star. It is the closest star to Earth

3 Have Scientist Seen A Star Die? Yes. In fact there have been a recent explosion of a star that has broken the record of the most brightest explosion Yes They Do! Stars live for about 10 billion years. When they die they could turn into a black hole or just explode! Do Stars Die?

4 How Do You Know How Old A Star Is? You can tell it by its colour. If it is a red star it means it is old. The Temperature is about 3 000 degrees, which is cold for a star. If a star is white it means it is a new star. It is about 35 000 degrees.

5 INTERESING FACTS As stars get hotter they create a core. They are millions of light years away. - A light year is about 644 661.78 years of travel.

6 Interesting Facts Interesting Facts Did you know that you could be looking at a star that is not even there! This is because the light of the explosion is still travelling towards you! Did you know that you could be looking at a star that is not even there! This is because the light of the explosion is still travelling towards you! This means if you look at Earth all the way from Pluto, you will see Earth in the Ice Ages! This means if you look at Earth all the way from Pluto, you will see Earth in the Ice Ages!

7 This Happens Because: The speed of light does not seem that fast when it has to travel for 7.5 BILLION KM!! That is 0.000624 light years away!!

8 Interesting Fact Did you know that when you look at one star you could be looking at 400-1000 stars. This is because stars are so far away. They only appear to be one star to the Human eye. You can only see a cluster (a cluster is a group of stars close together) if you look through a huge telescope.
