27 Facts About The Sun That Will Light Your Fire

Did you know that the Sun is an almost perfect sphere with a difference of just 6 miles (10km) in diameter between the poles and the equator? It is by far the most important source of energy for life on Earth, so we thought it is worth sharing the most unbelievable fun facts about the sun that we are aware of. So, enjoy the following 27 sun facts.
