The sun is the only star in our solar system‚ and all of the planets revolve around it. The mass of the sun is equal to about one million earths. It can cause solar storms that interrupt much of our technology and means of communication. The amount of radiation that can reach Earth during a solar storm is particularly easy to reach on the north and south poles.
