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

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

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!".

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

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

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

[–] Piemanding@sh.itjust.works 2 points 2 months ago (1 children)

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

[–] niktemadur@lemmy.world 2 points 2 months ago

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.
