"That 5th moon really hammers home the idea that Pluto was, well, hammered home at some point," Brown said.
HOWSTUFFWORKS: Why is Pluto not a planet?
Brown often refers to the Kuiper Belt as the "blood spatter" from the solar system's evolution - like a forensic scientist analyzes the blood spatter of a crime scene to reveal the perpetrator of a violent crime, planetary scientists analyze the objects in the Kuiper belt to reveal the processes that shaped our star system.
And with the discovery of P5, and the high likelihood of more Plutonian satellites being discovered, Brown reckons Pluto is revealing its own crime scene of sorts.
"If the whole Kuiper belt is the blood spatter with which we try to reconstruct the whole solar system, the Pluto system is what happens when even the blood itself is ripped apart. Which, really, sounds pretty creepy," he concluded.
