It is, its just not too many people know about it. I was hoping that it would give people the "oooooohhhh, aaawwwwwww" feeling when they saw it.

Much like most people don't know that Pluto is now considered a Kuiper Belt object now. Its a little complicated, especially since most people draw the connection between the Disney dog and the planet.
There was also a time when we had 13+ planets, which I may be wrong but text books from around the early 1900's include objects like Ceres, while now also include Eris, Haumea, and Sedna.
