It won't. The celestial equator is centred on the Earth.

They don't. Or at least, no more than the slight asynchrony between core and mantle that already exists.

It isn't. Only a very slight knowledge of astronomy and a look at the night sky is enough to assure us that this hasn't happened.

From that table, predicted closest approach in 2012 is > 0.04 AU, with a chance of impact < one billion.
All things do not "travel to the centre of gravity and then back out again".
It seems there probably isn't very much to be alarmed about.
