    This may seem a bit out of the topic but why are all the stars, planets, etc. round- why not square, hexagon, etc.?

      Their shape is defined by the way they rotate or orbit. If you take a rock out of a river, chances are, it would be round. Whereas you take a rock off the edge of a cliff, it would be some other shape. It's the constant movement of their environment that makes a thing's shape. If you ever visited the grand canyon, you might know that glaciers shaped the canyon. Have you ever faced the wind? If you turn round and round, the wind comes in different directions. (well, at least to you). Planets, when they rotate, the constant pull of gravity from the sun affects all sides of the earth while it rotates. Over long periods of time, the earth get's it's shape.
      I admit-I'm taking a guess, but it's reasonable, right?
