Why are Titan and Ganymede not considered planets? They are both larger than Mercury.

Because they orbit a planet, which makes them moons. If they revolved around the sun WITHOUT orbiting another planet then they would likely be considered planets.

Why can't a moon be a planet?

It is still afternoon here... just turning 2pm. I have no idea what the evening will bring. :)

Any specific reason you want moons to be planets?

Or are yah just bored?

How can a celestial body bigger than a planet not be a planet itself? It makes no sense...

Not an ellipse.

Words are made up and can mean whatever we want them to mean... they changed Pluto from a planet to a dwarf. Why can't a moon be a planet.

Yeah, like the word "trolling", I could instead use the word "Bodhisattva", and it would be accurate.

Suppose you're right.

Except that would be wrong... Bodi sometimes Trolls but often does not...

Because they are moons, locked into orbit around Saturn and Jupiter.

That simply says how it is now... not why it is what it is...

No.

That is the answer.

The rest is just you being bored and asking stupid questions.

Planets collected in their orbits according to density of the matter and solar gravity at that time. It doesn't make physics sense for two to form so.
