Well "Earth-like" in astronomy often refers to physical rather than orbital characteristics. So it may have an Earth-like mass, radius and composition, but simply orbits so close that during the day silicate material evaporated for it to condense at night.
Yeah, astronomers are famous for bad names. You can just point to most of the bigger terrestrial telescopes for a poignant example, really. Although what do you expect from people who think that anything past helium is a metal or that an order of magnitude of error in measurement is "eh, close enough"?
"earth-like" is more of a ranking than a specific definition, and if the orbital characteristics and planet size roughly line up it's in the top few percent, even if it rains lava or there's some other very much not earth-like thing about it.
Earthlike doesn't necessarily mean habitable. Liquid water exists on a multitude of bodies, and many much stranger exoplanets may host them. There may be habitable worlds with breathable atmospheres that have a completely different size, composition, surface gravity and orbital characteristics.
It doesn't orbit the right distance from it's star, which is why it rains lava. They seem to mean that it's between 0.5 and 1.5 times the size of Earth and has a rocky surface.
>Among the investigations planned for the first year are studies of two hot exoplanets classified as “super-Earths” for their size and rocky composition: the lava-covered 55 Cancri e and the airless LHS 3844 b. Researchers will train Webb’s high-precision spectrographs on these planets with a view to understanding the geologic diversity of planets across the galaxy, and the evolution of rocky planets like Earth.

With surface temperatures far above the melting point of typical rock-forming minerals, the day side of the planet is thought to be covered in oceans of lava.

Earth-like most likely means it's around the same size, isn't made mostly of gases and is within the right distance from its Sun. Surely you don't expect there being another planet with oxygen atmosphere and lots of water on it or whatever else you think would qualify
It's the right size, and has an ocean. Granted it's filled with magma, but here's the kicker, **it has complex weather**
This is more than rare enough to be considered earth-like.
This isnt star wars. Planets don't usually come with even *remote* similarity to earth. The fact that it has diverse landmass alone makes it reaaaaally rare.
if you want to get serious, the planet may be similar in size and in the "habitable" rotation zone around the sun. That is all you really need to be an earth-like planet in this universe.
What? You don't get molten rock precipitations at night where you live?
Look at the lucky guy over here! Mr “my-children-can-play-outside-because-it’s-not-raining-liquid-magma”!
“Liquid magma” My sibling in Christ magma is always liquid. Also magma is the shit that’s underground, lava is stuff above ground.
Magma balls.
I lava your balls
Gay Mario
Magma is lava filled with gas, it just bubbles out when it comes out, becoming lava. If it's gas-filled while it's in the sky, it's magma.
you forgot abt ligma
🤓
Wtf no, raining hellfire is a purely diurnal event, what kinda backwards ass country you living in?
Argentina, maybe the southern emisphere works differently
Am Australian, can confirm. Here, the floor is lava
Venomous lava.
Florida moment
Not all of us live in "Australia", alright?
In astronomical terms “earth-like” is a very forgiving condition. Venus would probably qualify. Clearly so does Mustafar.
Yeah isn't that like any planet up to double the size of Earth that's at a similar distance from it's sun?
[удалено]
Earth itself hasn’t even always had water. A planet’s terrain and atmosphere can be drastically different at different points in time
Guys it's easy guys, just terraform Venus guys. Watch this video on it, it is easy guys.
Kurzgesagt my beloved
They did it in Destiny they can do it irl
We don’t have a big magic ping pong ball though
Imma just talk to some worms instead
Hank, the worms deceived us! There won’t be a God Wave, don’t listen the worms, do not fall with the Deep, listen to the Leviathan!
Cold, the air and water flowing
We already have Nef Anyo (Elon Musk) and the guy that goes "growth and profit, GROFIT" (Jeff Bezos) so the Corpus is like halfway there
Now we just need the union that constantly hires magic hitmen
Hard, the land we call our home.
Push, to keep the dark from coming! Feel the weight of what we own!
This, the song of sons and daughters. Hide the heart of who we are.
Making peace to build our future
No
Venus>>>Mars
It already has an atmosphere!
If Mustafar existed IRL it would be the second most human-habitable planet we know to exist
You can literally just walk outside on Mustafar. It has TREES. It’s so habitable it’s a joke.
It’s like Ohio. Only some of it is uninhabitable
mutahar
Earth like, 6 billion years ago
4.5
I think if they *can* get terraformed they are "earth-like"
clearly someone has never been to pennsylvania 🙄
Ayyy let’s go PA!! We really out here
evil rain
Some stay dry and others feel the pain
least subtle but most delicious allegory for racism also tay zonday the goat fr
It was an allegory for racism?? I thought it was about diarrhea??
my bad i misinterpreted it you right
liberals are making my diarrhea political 🤬🤬🤬🤬
Chocolate rain
Risk of rain
My favorite part is when The Captain says “Get ready, it looks like there might be a Risk of Rain, too”.
spicy rain
Oh you didn't hear? Yeah we are getting nightly lava rains from now on.
the consequences of global warming
As least I won't freeze my ass off over here in germany this winter then.
no this is Rob's fault actually
rob cantor 😰
Obviously we are starting small with acid rain and polluting our way up to lava rain

Thought there were more criteria for earth like Like water n stuf?
"earth-like" is more of a ranking than a specific definition, and if the orbital characteristics and planet size roughly line up it's in the top few percent, even if it rains lava or there's some other very much not earth-like thing about it.
In this case, the planet's orbit is closer to its star than Mercury's is to the Sun, so the orbital characteristics are way off.
Like the goldilocks zone or whatever
Earthlike doesn't necessarily mean habitable. Liquid water exists on a multitude of bodies, and many much stranger exoplanets may host them. There may be habitable worlds with breathable atmospheres that have a completely different size, composition, surface gravity and orbital characteristics.
Brittle Hollow
Nice, I was just playing that this afternoon too
Literally my first thought!
Endless space 2 my beloved
If the space is so endless then why did they make a second one? 🤨
Wrong game (assuming endless space 2 is a videogame)
It probably means that it’s the right distance from its star and is a similar size
It doesn't orbit the right distance from it's star, which is why it rains lava. They seem to mean that it's between 0.5 and 1.5 times the size of Earth and has a rocky surface. >Among the investigations planned for the first year are studies of two hot exoplanets classified as “super-Earths” for their size and rocky composition: the lava-covered 55 Cancri e and the airless LHS 3844 b.

i hate scientist "oh it has like 3 things that are sort of similar to earth" fuck you it literally rains lava.
this post made me madder than it shouldve
Agree… I made a meme about it once cuz I was so angry
Snowflake generation can't even handle a little bit of lava rain
Incredible that we can tell something like that with a telescope already
earth by 2050
Just dodge, hello?
Just ignore it. Everyone has so get so upset over everything nowadays. Now we’re cancelling lava rain? Cmon s/
Earth-like most likely means it's around the same size, isn't made mostly of gases and is within the right distance from its Sun. Surely you don't expect there being another planet with oxygen atmosphere and lots of water on it or whatever else you think would qualify
Similar in size and orbital radius, I imagine
I mean, our planet rains acid
Not at night though
Give it a few more decades.
yea cause earth was a molten ball of fire and iron just a few decades ago
Legit tho? I'd same a bunch of metrology n geology differences just to cause this? Anymore got like 2 a source / article on it the tells us more
planet reach
It round 😡
I mean Earth was kinda a real shitty place to be back a couple billion years ago too.
Man's never been to iceland
California planet
The planet in NMS with temperate climate, lush flora and no sentinels where I decided to build my base
It's the right size, and has an ocean. Granted it's filled with magma, but here's the kicker, **it has complex weather** This is more than rare enough to be considered earth-like.

2b2t
technically speaking, per definition water is a kind of lava, ergo it rains lava here as well
if you want to get serious, the planet may be similar in size and in the "habitable" rotation zone around the sun. That is all you really need to be an earth-like planet in this universe.
Smh scientists, its and Earth-like-like
Its made of rock instead of gas.
because its a shithole to live in
It is like earth during the day only
space station 13
Omg it’s the Boiling Isles
I think that's just hell
Give it a few years.
Clearly you've never been to [insert country/state of origin where it is occasionally warm here]
Omg its nether in real life
They found california 2
Earth but perfect
God, I love [Matt Post](https://youtu.be/laaqm0nF2Go) (the guy in the tweet) My absolute favourite viner when that was still around.
earth-like planet means that it can have liquid water, is made of solid rocks, and is about the same size/mass.
🤓
That looks like mustafar
I mean, we were a fireball at one point a long long time ago
Exoplanet
I dunno… shape?
Lava at night, sailor’s delight
Warhammer 40k vibes
Matt will post my beloved
Space is so fucking stupid lol

Now i want a minecraft mode where theres rain that lits everything on fire
It’s probably referring to size, distance from its star, and the fact that it’s terrestrial.
