Planet earth revolves around the sun in a whole year. The earth would not exist if it wasn't for the sun.
What is the sun?
The Sun is a ball of plasma, helium and hydrogen. Loads of people describe it as a huge ball of gas and fire.
What is the suns job?
The Sun's job is to heat up planet earth. When one half of the earth is dark and one half is light, the light half is day time and the dark one is night time.
No organism on planet earth would be alive if the sun is not around.


The Sun
The Sun is a huge star at the center of our Solar System made from hot plasma. It is roughly 4.5 billion years old! It's diameter is about 1,392,000km big, roughly 109 times bigger than Earth's. Chemically, about three quarters of the Sun's mass is made of hydrogen (74.9%) and the rest is mostly helium (23.8%). Parts which are not helium are heavier elements including oxygen, carbon, neon and iron, among others (less than 2%). All of this is held together by gravitational fields.
