That's nothing new! Consider Titan, which is bigger and more massive

Yet, it's not a planet, because of its orbital characteristics: it
orbits Saturn, not the Sun.
Based solely of the physical nature of the object itself, Titan would
be an obvious planet. Right?
Right, unless the limiting mass for a planet is reduced to a level
that would exclude Titan, in which case Mercury would not be a planet
either.

I think you mean "increased" rather than "reduced"..... :-)
Anyway, no-one has seriously suggested THAT - right?
