“Whether or not the moon is a planet actually depends on who you ask,” Skylar Grayson, an astronomer at Arizona State University, told Live Science. The 2006 IAU definition “draws a fairly arbitrary line between planets and dwarf planets that (in)famously led to the demotion of Pluto,” she added. “Some planetary scientists thus elect to consider different definitions of planets, some of which include Pluto and the other dwarf planets, and others that even include the moon.”

why does it need to be complicated? It orbits a planet, therefore it is a moon.
(yes I know this is not technically an accurate statement. They each orbit the barycenter, but that is basically still in the earth.)
The real history of moon is in this song.
We’re whalers on the moon,
We carry a harpoon,
For they ain’t no whales
So we tell tall tales
And sing our whaling tune.This QVC host was streets ahead of his time.
Why does it get so downvoted? Is it just because it’s an unexpected idea? I think it could be an interesting discussion. Is Charon a moon? How about Ganymede and Moon? They are bigger than Mercury… Of course nothing will change, but the discussion might be interesting. And personally, I wouldn’t mind living on one of the binary planets, if it was useful.
