Earth is the homeworld of the human race. It is the UNSC's last bastion of power, since Reach fell, and is heavily protected with Super MAC orbital platforms, over a hundred heavy cruisers, and many other experimental defense systems. The UNSC have taken no chanches with keeping the secret of Earth safe, though it was only a matter of time before the Covenant discovered Earth's location. Thousands of miles worth of cities have been built because of population grouth. The surge of population is one reason why the UNSC became making the "Inner Collonies".
