A planet after all

A while back some of us at work were discussing whether Pluto is a planet or just a Kuiper Belt Object. That day's final word: "Of course Pluto's a planet! It has its own Sailor Soldier!"


Well, Pluto also has moons! Yes, plural. Not just Charon, but two much smaller ones - which may even shepherd a thin ice ring around Pluto. So far, they don't have names (they're just S/2005 P 1 and S/2005 P 2), but here's a nice Hubble shot of them:



So. The Sailor Soldier argument is a bit weak (after all, the Moon has one and Earth doesn't) even if she is an Outer System Senshi, but if Pluto has moons and a ring, it's a planet.

It has to be.
