When looking for habitable planets, there are a couple of things necessary for life
00:07
to survive there.
00:08
Things like atmosphere, ideally with oxygen, it has to be in a certain range of a heat
00:11
providing star, and it needs water.
00:14
And for the first time ever, astronomers think they've finally found a super-Earth exoplanet
00:18
that has all three.
00:19
Angelo Siaris, an astronomer and lead author of the report, said in a press conference,
00:23
�This is the only planet right now that we know outside the solar system that has
00:26
the correct temperature to support water.
00:28
It has an atmosphere, and it has water in it, making this planet the best candidate
00:32
for habitability that we know right now.�
00:34
They're calling it K2-18b, and it's 110 light years away, tucked in the Leo constellation.
00:40
It orbits a red dwarf star that's about a third our sun's mass, meaning it has shorter
00:44
years, orbiting in just 33 days.
00:46
But K2-18b is big, roughly eight times the size of Earth, and made of similar compounds
00:52
as the Moon and Mars, which astronomers say, because of the detection of water, could mean
00:56
an ocean covers its entire planetary surface.
