The sun is a giant ball of gas that is held together by gravity. its is 5,778 K and thats just the surface! Its heat brings life to our planet and its gravity protects us from powerful forces without it we wouldnt even exist and if it were any closer we would be fried and turned into dust. But dont be fooled by how it helps us it is a killer to other planets, and to find out how the thing that gives us life can be the end of life itself read on

The sun is the key substance to life on our earth but even though its the thing that keeps us alive it can also be the thing of our doom! Our distance from the sun is the best it can be because if any closer it can be our destruction! the sun is at a length were it takes 8 minutes for its light to reach the earth you may think thats close but it is way further than you can imagine it is 149,600,000 km away from our earth. Lets think if it was 500,000 km away from our earth. If it was like that water on the earth will disappear in a instant the earths crust will burn to a crisp wouldnt be a good life will it. Now lets think if it was 200,000,000 km away! The earth would be a negative number every day the ocean would be frozen and will be impossible to chip away and all metal on the earth will turn to rust so we should be glad that our sun is close and not too close.

The Sun May be a hot head but even though you think its hot on the outside your wrong. the sun has a number of different layers that our hotter the more closer you are to the core those layers have been summed up into 3 layers the convective zone, the radiative zone and the core. The convective zone is basically the outside of the sun were all of its heat energy gets sent out by the radiative zone. The radiative zone is the radioactive part of the sun and it gets the energy from the core and brings it to the convective zone it is at least 2 times hotter than surface. But then we have the core it is hotter than any part of the sun and is the place which creates the heat and energy that brings life to our planet

A solar flare is a sudden powerful of energy that is so powerful that it take 160,000,000,000 megatons of TNT to be equal to its destructive power it occurs when many powerfully charged electrons hit plasma particles and a lot hit each other creating a heap of energy that is transmitted into a solar flare! So lets hope no solar flares hit our planet

The sun may be in the sky but where is it in the sky? The sun is actually in the center of our solar system and the order of the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto and they all spin around the sun by its gravity. But before they found out that the sun was at the center they believed that that the earth was at the center of the universe and all the planets spin around it which they called the geocentric model. But they soon found out about gravity and that earth or the sun isn't at the center of the universe but that there our solar systems and galaxies that spin with the power of gravity. So all the things we know could all change by learning one thing!
