The Sun

There are billions of stars in the universe, yet there is one that out weighs all the others in importance to us and is studied far more then the others and that one is known to us as the sun. It is pretty obvious why though that one star is responsible for life on this planet and is way closer to us then any other star. This colossal mass is actually considered a pretty average size among stars, but in terms of its importance to us it is larger then all the other stars in the universe. Imagine if this star didn't exist none of us would it's a crazy thing to think about. Isn't it?
