A person who sets norms for what is or is not a planet, a star, a galaxy, dark matter, etc.
At a 24 August 2006 international meeting of Earthling astronormers, it was voted that Pluto is not a planet. After the news reached Pluto (several hours at the speed of light), a hastily called meeting of the Plutonian Astronormical Society unanimously proclaimed that Earth is dirt, and that Earthlings are full of worse than that.
