The earth is big and heavy and full of iron and stuff.  It smooths out
the fuzz in the sun's magnetism and keeps a lid on the magnetic
typhoons.  Otherwise the sun would be flipping its poles every day.

Nasa studies all this.  Check there website.

They also said earth rotates around its axis, not the sun.
