M.J. McGuire - Pluto

In an act of sinister and celestial Judo
They’ve recently reduced the size of Pluto.
It’s no longer on the planet list
-Nor are the moons within its midst.
It’s become a ho-hum planetoid,
An irksome, king-sized asteroid.
Hail the wonks at the planetarium!
(Who altered history for an honorarium) .

M.J. McGuire
