grrgyle,

No way!

abcd,

Is Neil deGrasse Tyson hiding somewhere in Australia?!

Dudewitbow,

introscene for the next mecha anime confirmed

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.

lolcatnip,

Or does it mean Australia is a planet?

faceula,

Sand Mass?

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

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

some_guy,

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

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

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.

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!

The Alice Springs Pluto Observatory has opened considerably under-budget.

intensely_human,

That’s an avocado pit and you know it

CM400,

Wow, Pluto has approximately the same surface area as Russia

HootinNHollerin,

And now putin starts pumping out propaganda that pluto used to be russian

Numenor,

Do it.

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

Honestly never had a clue. Thanks for the share.
