Do you still consider Pluto to be a planet?
Does Pluto still need love or can we finally let it go?

A true planet, according to the IAU's newly devised definition, must meet three criteria: It must circle the sun and no other object, it must be big enough to be rounded into a sphere or spheroid by its own gravity, and it must have "cleared its neighborhood" of other orbiting bodies..
Pluto failed at this because its neighborhood the ring of icy bodies "Kuiper Belt"馃檮
"clear your neighborhood" requirement seems ridiculous to me 馃

@suchaslife Well that distinguishes moons from planets, or objects like Pluto that are binary systems.
