Probably a couple more.

Nope, Pluto is bigger than Charon.

I am not sure that a moon can be bigger than the planet it orbits around.

Two objects would orbit around the same center of gravity which would be closer to the more massive object.

Which is the current situation of the Pluto-Charon-Nix-Hydra-S/P2011-S/P2012 system. They all orbit 1 center of gravity that lies outside of, but is closest to, Pluto.

The Sun - Earth system has its center lying inside the sun, and so does the earth-moon system whose center lies inside the Earth.

I love that app. I remember trying to make a stable 3 body system in it.

What is more important is that it just recently lost 2 moons.

So, the event 'Pluto recently lost 2 moons' is more importanat than 'I can only find 3 Pluto moon names'. That means whatever the number is, it was already a reduced number. Right?

Not exactly. She was saying she can only find three so I was saying maybe it recently lost 2. In the last 2 days or so.
