Important facts
About the sun
v Largest: If the Sun were as tall as a typical front door, the Earth would be about the size of a nickel.
v Most Massive: The Sun is the center of our Solar System and makes up 99.8 percent of the mass of the entire Solar System.
v Different rotations: At the equator, the Sun rotates once every 25 days, but at its poles the Sun rotates on its axis once every 35 Earth days.
