Heh, well some familiarity with cosmology is assumed. All (AFAIK) supermassive blackholes are in the center of galaxies.

By my math 99.987% of the universe is further away than 12 million light years. As mentioned in the article it's so big that from earth it's 16 times larger than the moon (as viewed from earth of course).

Seems reasonable to consider 0.012% of the universe "near earth" when talking about galaxies or blackholes at the center of a galaxy.
