Pluto only has .08 % of the moons jupiter has.
Also, Pluto can't be considered a planet because it's mass is enough to give it the required gravity to clear the path around it's orbit so that it adds up to 2/3rds of the mass in it's orbit path.
I only thought Pluto had one moon, Charon. Does that mean the Sol system has 5 mass relays?! :v:

Nix and Hydra were discovered around 2008-ish. Not sure about p4.
I love how we're only now finding that Pluto has a 5th moon. Imagine what else we haven't found.
A funny thing is that Charon is so massive that both Pluto and Charon are orbiting a point in space between them (barycenter).

So in essence, they are orbiting eachother.

Well, all planets and stars do that. There is a barycenter between the sun and earth as well. The earth doesn't just orbit the sun, the sun also wobbles from the gravitational pull of its planets.

Well yes, but what's different for Pluto and Charon is that the barycenter is actually outside of Pluto.
Which is neat.
You all know the line...

i alreadly foind it but never told noone
The fact that we still haven't mapped out our own solar system goes to show just how inconceivably large and dark most of the universe is.
No wonder they haven't discovered it earlier, the diameter of 20km is nothing.
[QUOTE=DesolateGrun;36723441]That means it didn't clear its orbit yet thus not meeting the criteria for planets
Give up planet scrubs[/QUOTE]
Puto is a dwarf planet, which is a subcategory of planets.
So there-fore it's still a planet.
the orbits remind me of an atom

What joke?
Truly a remarkable feat for astronomy, this moment shall be glorified in history, known by everyone of Earth.
[QUOTE=Jurikuer;36724030]Charon is larger than the Relays are. The Relay was encased in Ice.[/QUOTE]Wow, and those relay's are enormous too, damn..

Ha that's too neat.
