Our own star that supplies our heat and light is between 91 and 94.5 million miles from Earth. Our orbit is elliptical. The distance between us grows larger and smaller throughout the year.The sun is only average size for a star, yet it's size is another terrific source of astronomy fun facts. It's contains 98% of all the stuff in the solar system, even though it's not large for a star. Everything else, counting the earth and all the planets, is a tiny 2%. It would take about 100 Earths to make it across this average sun. The solar wind produced by the sun extends to about 50 times the distance from the Earth to the sun from the sun. In other words those solar winds go out about 50 AU's, with an AU being the distance from the Earth to the sun.
