Also... to refute a common refrain here. In two ways it is possible to demonstrate that, while not the centre of the solar system, the Earth IS the centre of the universe.
Method one:
Since we are on the earth, and all of our observations are made from here, we are the centre of that part of the universe we can preceive. Therefore, on a perceptual level, the earth is the centre of the universe.
Method two:
1. The universe is infinite.
2. In an infinite space, all points are equidistant from the edge of that space.
Therefore all points in the universe can be said to be at the centre. The Earth is a point, therefore it is the centre of the universe.
