The Sun

The sun gives Earth life,food and light.

The sun is the closest star to Earth. The sun is not a old star,it was born about 4 and a half billion years ago. The Earth could fit about one million times into the sun.

The sun orbits the milky way it will take 250 million years to orbit the whole milky way. The sun is one of the brightest stars in the universe. The sun is made of mostly hydrogen. On the surface of the sun it is 5000 degrees but the core is extremely hotter.

The suns sunlight takes about 8 minutest reach Earth and if this did not happen we would not be here on Earth.
