What is Pluto doing so close to Australia?

That shouldn't be allowed. Someone tell it to go back to it's usual orbit, this is not on.

You didn't know they had a thing? It lasted until Australia found out Pluto wasn't really a planet.

Still, the surface area is much bigger. Pluto is a real continent

Discreetly insulting both Australia and Pluto in one sentence! Absolutely love this; will share it with all my Australia and Plutonian friends! If Earth gets attacked, it's not my fault, but yours :'P

Australians can’t attack Earth, they’d fall right up into the sky without some reverse-reverse-gravity system.

When they came for Pluto, I said nothing because I wasn't a planet
When they came for Australia, I said nothing because I wasn't a continent
When they came for Bielefeld, I said nothing because I wasn't a city
When they came for me, there was no one left to say anything

Australia would have to round up its edges and clear it's orbit of little islands before being called a planet.

If that photo was taken right before impact, none of the continents will remain continents because it's all about to melt and we might have another moon when everything settles down and we evolve back from scratch over the next several billion years.

It never was. The concept of Australis is part of spherical world order.

Do you really think a Platypus is a real animal? A mammal that let's eggs and has bioluminescent fur. Get the fuck outta here.

Pluto is still a sphere, this is an unfair comparison because Pluto hasn't been unwrapped

Fun fact: the surface area of Pluto is only about 4% larger than Russia.

Even more amazing that it was found in the era it was. People were pouring over the skies looking for the next big planet, and instead they found this little guy.

There are still some orbital dynamics suggestions that something large and dark is lurking out there -- an ice giant. But it's still largely conjecture. It'd be interesting to see how they define it should they find something very large (say Neptune mass), but it hasn't cleared its orbit. Is it a planet or not? :D

Actually 🤓 it was James Cook who found Australia and he didn't go there by ski but by ship and he didn't find one little guy but exterminated a whole indigenous population

They only found it because it's more like a binary dwarf planet system than a planet/moon system, so the telescopes were able to pick up light reflected from both Pluto and Charron, while Pluto alone might have not been bright enough.

No! Austria will never be a planet nor continent. It is a white, European country and I'm willing to die on that hill!

Absolute size isn't really in the criteria for a planet though. Pluto isn't a planet because it shares its orbit with lots of other icy bodies in the Kuiper belt.

Exactly. That's also why Jupiter, which shares its orbit with thousands of asteroids, isn't a planet either.

Do you mean the Trojans? They're excluded from the mass calculation of 'clearing the neighbourhood' because they're in a resonant orbit - their orbit is a consequence of Jupiter's mass.

I don't know. I don't think we should make excuses for Jupiter just because of its size. Pluto's doing the best it can. Could any of us do any better, so far out from the sun?

Jupiter does throw its weight around a bit too much.

Thanks to your comments, I went looking at more about Jupiter's influence on us and read that most of the other planets are more in line with Jupiter's orbital plane than the Sun's equatorial plane (which sounds impressive, but maybe only makes complete sense since the planets would have all initially formed from the same disk). Anyway, thanks

That's really interesting!
I just discovered a theory about the cause of the 'late heavy bombardment', which is thought to have delivered water to earth via comets.

Essentially the gas giants all orbited much closer, but Jupiter and Saturn got into resonance and flung Uranus and Neptune way out (and Saturn too). Uranus and Neptune flew out into the path of a heap of ice, and their gravity pulled the ice into an orbit that collided with the terrestrial planets.

As a former Plutonian, I can confirm it's small, that's why we immigrated to Earth. And fucking cold!

Stop posting pictures of my family, they are very shy!!!

Small little fucker, no wonder it’s not a planet anymore.

Then again it could be super close and the size of a potato.

They are if they are moving towards you really fast!

Nah, no one likes lives in that part of Australia. Pluto sitting there just means drivers from Perth to Sydney have to take a little detour.

I mean, I'm pretty sure you'd be able to see it from everywhere in Australia, so I bet many of them would be like "WTF?" But they'll be dead soon. Fuckin' kangaroos.

Hey wtf put Pluto back to where it belongs. Do you have any idea how bad this is for the world economics???

Is Neil deGrasse Tyson hiding somewhere in Australia?!

I saw him in my mates house the other day kissing a mirror? He said he is the only person he can kiss in the mirror or something.

2

That's awesome. And to think, it's only slightly less inhospitable in Australia!

In future news; Donald X Musk III, worlds first quintillionare, decided to alter Pluto's orbit to collide with Mars "Becauth it would be thoo cool!".

I can see why they no longer call it a planet, what's the cutoff for asteroid size?

I'm digging the way the map shows Tasmania as part of the continental plate.

2

The light blue part is shallow and when it's underwater, they call it "continental shelf".
Tasmania and mainland Australia are connected by the same, shared continental shelf.
