In the last stages of the formation of Earth (4.5 billion years ago), it may have been struck a few times by objects about the size of Pluto (1,500 - 2,000 miles across). Earth has not experienced anything like this impact since that early time.

Infrared light passes through much of the dust in the Galaxy allowing us to see more of its structure than we can with our eyes. (Image credit: 2MASS/J. Carpenter, T. H. Jarrett, & R.

The magnetic poles are not aligned with the rotation (geographic) poles of Earth. The location of the magnetic poles changes with time and even flips with respect to the rotation poles over geologic history. In the current era, the magnetic pole in the northern hemisphere is a south magnetic pole, which is why the north pole of compass needles point in that direction.

This perspective is from above the plane of the Solar System and we can see the two different lines of sight from Earth to the Sun and from Earth to the Galactic center. Also note that there is no alignment of planets on this date, which some 2012 doomsday theorists claim.
