This is a lot of hype to say that a planet, an object which orbits a star, is a planet. Anyone who has been seriously looking at stars and thinking about what makes up the universe has come to the conclusion that the thing that orbits a star (and has all the other criteria of a planet) is a planet, even if the star it’s orbiting also orbits another star.
Likewise, the idea that a moon can have a moon has been discussed. The problem is that the rules for what constitutes a moon make it hard for that to happen so, given the size of the Milky Way, there’s probably a number of examples out there.

We could call objects orbiting moons, moonies!
We could name an award after it!
Oh, wait…
