What is “surface”?
Also, what is “landed”? And why is Jupiter out? (Edit: Or the Sun, for that matter.)
What planet has Jupiter landed on?
What is “surface”?
In this context, I believe this is limiting to planets whose water is not deep inside the planet’s crust somewhere, but exposed to its atmosphere.
Ok, but the gas giants should have that. We just can’t see them.
Unless you want pure water. But then, how pure?
Since categorizing something as a planet means nothing then traditionalist is the only way to go. If Mercury is in the same category as Jupiter and a sudden orbit change can mean a thing might no longer be called a planet then there is no scientific value in calling things planets. They are just traditional names given to fairly random objects like constellations.
So, expansive then.
I would personally categorize everything with a high enough gravity as a planet, i.e. everything that can hold an atmosphere or sth.
…the highlighted bodies under Lunar are wrong. Charon isn’t a moon it’s a dwarf planet in its own right. The barycenter of it’s orbit isn’t inside Pluto. Pluto and Charon are binary dwarf planets not a planet moon pair.
Who put all this color in my XKCD?
I’m partial to Tom Cardy’s view: Pluto isn’t a planet, but that doesn’t matter because it’s still hot shit.
Empiricist is a very solid take tbf
Simplistic was basically the original proposal for a planet before it was highjacked on the last day of the convention by a bunch of scientists with an axe to grind.

They forgot about bofa . They are the only planets
I’ve been in the Expansive camp for a while.
That’s messed up.
Love it, especially the alt text.
only pluto is a planet, I am spiteful
It’s only a planet if we could walk on it. What would the name for that one be?
Pedestrian
I’m partial to the simplistic view: big enough to be round, not big enough to fuse hydrogen
Technically tiny amounts of Hydrogen fusion will happen in the gas giants.
I’m sure there’s a sensible line to be drawn somewhere
Since people have fused hydrogen on earth, I choose to believe it’s not a real planet
All those who wander are planets.
