Pyr_Pressure,

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

johannesvanderwhales,

It is still a dwarf planet. Basically when it hits hydrostatic equilibrium, i.e. when it’s round, it is considered a dwarf planet. More here

Freefall,

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!”.

Etterra,

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

Meanwhile, Australia is down there like “WTF mate?”

milicent_bystandr,

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.

MonkderVierte,

TIL australia has hydrostatic equilibrium.

niktemadur,

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

Piemanding,

Is it on purpose or is it because of ocean depth?

niktemadur,

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.

grrgyle,

No way!

abcd,

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.

Dudewitbow,

Burn_The_Right,

So… Does this mean Australia is no longer a continent?

Murdoc,

Dwarf continent

Buddahriffic,

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.

Burn_The_Right,

The only survivors would be Australia’s infamous Magma Spiders.

P00ptart,

Just in time to get baked by the sun!

lolcatnip,

Or does it mean Australia is a planet?

Burn_The_Right,

I’m sure the rest of the world would agree!

jol,

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

faceula,

Sand Mass?

Landless2029,

Seems like it amounts to a gas giant down under.

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.

First they came for Pluto’s planethood.

Next they’re coming for Australia’s continenthood.

lugal,

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

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

UnderpantsWeevil,
@UnderpantsWeevil@lemmy.world avatar

It’s actually 4π*(0.5*(length-of-australia))^2 bigger than that.

doctordevice,

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

RandomVideos,

So thats why Russia wanted to expand

NigelFrobisher,

Pluto unboxing video.

some_guy,

No shit? Wow, it’s amazing that we were even able to find it.

troyunrau,
@troyunrau@lemmy.ca avatar

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

lugal,

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

troyunrau,
@troyunrau@lemmy.ca avatar

Ah shit, a switcheroo!

Buddahriffic,

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.

This picture is inaccurate, Pluto is actually much farther away.

mindbleach,

Telephoto shot, using a 1e50 mm lens.

Swedneck,
@Swedneck@discuss.tchncs.de avatar

if anyone wants to do the math, how far away from the sun would the camera have needed to be to take such a photo?

mindbleach,

Apparent scale is inverse linear, i.e., proportional to 1 / distance. If we want the apparent scale of two objects to be about 90% accurate to their actual relative scale, their relative distances to the camera can’t be more than 10% different. Pluto being 40-ish astronomical from Earth, you’d want to shoot from about 400 AU. Voyager I should be in prime position circa 2140.

lolcatnip,

Probably not necessary to use a lens so long it can reach distant galaxies!
