Proposal: Uranus et. al. should no longer be called "plane-ettes".

[Khedrac]

But we do already have a special designation for Neptune, Uranus, Saturnus and Jupiter. They're all gas giants.

That's what I grew up being taught, but it's not what they are now!

Jupiter and Saturn as 'Gas Giants', Uranus and Neptune are now 'Ice Giants' whatever that means.
