I-is it called Pluto by chance?
>planet is a social construct, the distinction between dwarf planet, planetoid and planet are arbitrary classifications not based on scientific fact but on orbitism.
>That far out
Fucking crimity. It's probably just an extremely cold, barren, gray piece of rock. Could any planet with an orbit and distance away from the sun really have much going on with it?
You could have said the same thing about pluto and it's got more going on than a lot of shit in the inner solar system.
Also, reminder that Neptune was first inferred through indirect observation before being confirmed.
> x10 earth
The size is scary though. Also why is it too dark ? Is it the atmosphere or the actual rocks on the surface are that dark ? Or is it just a digital representation and the planet actually looks different.
How so? I can only imagine that it might if it has a ton of geothermal activity creating a temperature gradient. After all, Neptune is incredibly cold yet the winds aren't necessarily "hellacious".
>tfw it is nowhere near the sun right now and won't be for at least 5000 years so it won't send any comets our way in our lifetimes
It's literally just a drawing some artist came up with, so they had an image to attach to the article. It has no real basis on fact because no one has any idea what this planet looks like, if it does exist.

At that distance it must have the biggest gravity well in the solar system, right? Therefore it might have captured a shitton of bodies, even some the size of Sedna.
Also the thing is supposed to have a 30° inclination and a pretty eccentric orbit, anyone else think it sounds like a captured exoplanet too?
you are right, I shouldn't use words like 'size'.
Assuming Planet 9 is an ice giant with an approximate density of Uranus (1.27g/cm), the Volume of Planet 9 would be 5.972e28cm^3 if we convert the Earth's Mass into grams and multiply it by Uranus' density.
Using v=(4/3pi)r^3 and converting back into metres gave me a radius of 24248063.756m, or x3.8 the radius of Earth.
Isn't there a strong theory that assumes that there used to be an Ice giant between Saturn and Uranus that was ejected by Jupiter, based on the current arrangement of the solar system ?
I just find it hard to fathom how Jupiter could send a 10 earth mass planet on an orbit with such a high perihelion on a 30° inclination. It's not impossible but it seems like a bit of a stretch.
Whereas for a captured planet it makes sense easily.
look into the absalutly ridiculous mass of jupiter, now imagine the planet was between Mars and Jupiter, maybe it began forming somewhere near the Martian orbit, because both bodies had a high gravity they were pulling on each other and jupiter inevitably won.
As you said, it definitly isnt impossible, and in a young solar system I can see this happening as each time it passes its orbit becomes more and more eccentric until it is just pulled the fuck away, because once it gets the far side of Jupiter it still has Saturn and even Uranus is quite a massive planet both of which could have helped stabilize its orbit.
The paper the article cites says there is only a .007% chance that the perihelion and clustering of the other distant kbo is caused by chance so if it isn't a planet it has to be something. What?
Dark Matter doesnt form celestial bodies because it doesnt interact with other matter (think neutrons not reacting with matter unless hitting it directly because of no electrical forces)
Jupiter is 317 times the mass of the earth, so nearly 32 times as massive as the proposed planet. That combined with additional gravitational pull from Saturn and possibly the other gas giants makes it a fairly realistic scenario. But the possibility of it being a captured exoplanet is valid too, it just seems unlikely an object of that mass would be flying by the sun at such a far distance and enter an orbit rather than just having its trajectory changed and continuing onward through interstellar space
Two of them, X2 and X3, are gas planets, one is about half the size of Jupiter and the other is about half the size of Neptune. Both are in the outer (spherical) part of the Oort Cloud. The third one is a solid matter planet which is only slightly smaller than Earth but damn far away for a visit.
You mean someone found Pluto again?
>it changes it's orbit and starts moving toward us
>it opens its eye
Assuming that you referred to Hercules, it's not bad, for a planet flinging the shit out of other planetoids just by making its way through the solar system.
But Hercules was just a demigod, doesn't make me fully satisfied.
I like this idea.
"god of beginnings and transitions, and thereby of gates, doors, doorways, passages and endings"
Pretty much Nibiru-ish
My favourite by now.
How is this different from all of the previous times some astronomers have gone "There's something funny with these orbits, they're being nudged by the gravity of a current planet count + 1th planet?" I mean yes, that's how we found Neptune and Pluto (Although that was partly just luck on Pluto's part) but there's been numerous other claims over the years that have amounted to naught. Call me back when they've actually spotted it.
Plus the binary companion.
Enough for tons of papers.
Is Hecate (or Hekate) already taken?
(/ˈhɛkətiː, ˈhɛkJt/; Greek Ἑkάτη, Hekátē) is a goddess in Greek religion and mythology, most often shown holding two torches or a key and in later periods depicted in triple form. She was variously associated with crossroads, entrance-ways, dogs, light, the moon, magic, witchcraft, knowledge of herbs and poisonous plants, ghosts, necromancy, and sorcery.
>meme magic planet
I guess you're right. It just fits too damn well.
I might be remembering this wrong, but didn't the Plutocaust people decide that trans-Neptunian bodies would be named after the Ice Nigger gods? If so, I have a grand proposal.
In fact, even if they DIDN'T make that a rule, my proposal stands. I humbly present, for the consideration of the internet: "Negafook." Negafook is the god of the North Wind, and of general cold/storminess. So it would actually fit reasonably well. Also, Uranus has been the most-abused celestial name for far, far too long. It's time to let somebody else be the butt (huehue) of our schoolchildren's jokes. Negafook; think different.
also, I mean, come on. Look at this fucking nigger. I mean, niggafook. It's never going to get better than this. And we're never going to have another chance to do something so grand. Write your congressman. Write the scientists. Call your mothers. Negafook. Negafook. Every day until they love it. Until YOU love it. Negafook
There's more than one planet X and Yuggoth should be the name of most distant one.
The predicted companion of the Sun also deserves a powerful name.
But would a brown dwarf count as a planet?
Star systems: 75% binary, 22% ternary, 3% single, very few 4&more.
Fun Fact: It isn't a planet in orbit at all, it's a rogue planet on its way to tear through the solar system and either pull us into a terminating orbit with the sun or swing our planet into the freezing depths of deadly space.
These "nomad planets" could be surprisingly common in our bustling galaxy... The study predicts that there may be 100,000 times more of these wandering, homeless planets than stars in the Milky Way. (space.com)
Venus once was such a wanderer, 'born of Jupiter', captured about 80k years ago. Maybe.
>that part where they went on the surface
In my opinion that was the creepiest atmosphere Ito did ever
>Call me back when they've actually spotted it.
Don't hold your breath. We really only spotted Sedna lately since it was pretty much at perihelion. There could be dozens of Sednas out there, which implies a handful of Earth-sized bodies in the same volume.
The detection specifications are a graph... meaning you'd expect a lighter body closer in, or a heavier body further out. So you don't even know what size you're looking for.
Better telescopes are needed, and those should be "Keplerized". The Kepler probe has been so productive since it was set to stare at one patch of sky all the time. Then again, we'd need about 400 Keplers to distribute such a stare across the entire sky. A single Kepler had a lifetime cost of $600 million; even sharing mission resources, at best it would cost $100 million per Multi-Kepler, hence $40 billion lifetime cost. There's no budget for such a thing.
>Lets say there is an object the size of the earth somewhere at the Kuiper Belt. What wold be its angular aperture as seen from earth?
Kuiper belt extends from 30 AU to 50 AU, so let's say 40:
About 0.4 arc seconds.
>During planet formation, rock and ice embryos of the order of Earth's mass may be formed, some of which may be ejected from the Solar System as they scatter gravitationally from proto-giant planets. These bodies can retain atmospheres rich in molecular hydrogen which, upon cooling, can have basal pressures of 102 to 104 bars. Pressure-induced far-infrared opacity of H2 may prevent these bodies from eliminating internal radioactive heat except by developing an extensive adiabatic (with no loss or gain of heat) convective atmosphere. This means that, although the effective temperature of the body is around 30 K, its surface temperature can exceed the melting point of water. Such bodies may therefore have water oceans whose surface pressure and temperature are like those found at the base of Earth's oceans. Such potential homes for life will be difficult to detect.
The possibilities are endless.
I already gave my opinion, we should call it after a christian saint.
no way to know yet obviously but it is a good question. I think knowing where to look will have a greater effect on finding it visually than its albedo though because it is so far away.
>Only the planet's rough orbit is known, not the precise location of the planet on that elliptical path. If the planet happens to be close to its perihelion, Brown says, astronomers should be able to spot it in images captured by previous surveys. If it is in the most distant part of its orbit, the world's largest telescopes—such as the twin 10-meter telescopes at the W. M. Keck Observatory and the Subaru Telescope, all on Mauna Kea in Hawaii—will be needed to see it. If, however, Planet Nine is now located anywhere in between, many telescopes have a shot at finding it.
Regardless, it will probably take a few years before we find it if it does in fact exist.
I was just watching a documentary on the wandering planets last night, bretty cool.
Didn't see anything about Venus not being from our solar system though. What was the evidence behind that theory?
It could be selection. i.e. only seeing the KBOs closest to the Sun where they move the fastest and are brightest hence most easily detectable. Also surveys don't cover the whole sky.
A planet could be orbiting at the edge of a system so fast that it could eventually sling shot its way out of the gravitational range of the star. Of course we've never observed that happening since it would be so relatively slow, interesting thought no matter what.
Mine it for resources for our ever expanding crusade into the Galaxy!
I understand that you can have planets flung out if they get pulled via other planets in the correct fashion, but what was the exact reason for suspecting Venus of being from another parent system?
It's likely to be an Ice giant, Neptune and Uranus are of similar mass to it and they are Ice Giants. our Gas giants, Jupiter and Saturn are many times larger than Neptune and Uranus. It's possible it may be a Gas giant though.
What spectrum would this thing be the easiest to see in? Visual? Infrared? I was reading earlier about JPL's WISE and how it looked at the entire sky but Planet Nine wouldn't be able to be seen by it. Would JWST be best suited to see it?
It would be brighter in the infrared but visible is easier to get deeper (because on the ground the sky is very bright in the infrared and there is really only one major infrared survey telescope).
JWST is poorly suited to finding it because it has a tiny field of view and it isn't well known where it is. It probably isn't that faint (if it exists) but just finding it would be a serious change.
I just realized planets are realms and space is the aether
How come when science discovers something religion has theorised since forever they give it a new name and act like it's something different? They're like
>SEE you were wrong cause it's not a realm it's a PLANET
If we ever find God scientists will call him something different just to claim theists are wrong.
It will be interesting to see if they find it. Its an old theory and finding it would be huge news. We dont know if there is something there or how large it is. Only fact is that it was called Nemesis so far even tho it was for brown dwarf as you said. Might end up as Nemesis in the end.
Sure looks like it's clearing its orbit to me.
Clearly false as the planet depicted is orbiting a binary star system.
I don't think it is a planet just orbiting our sun. In fact, I don't believe it is orbiting at all. Do you think it is a coincidence we are just now discovering it? It is Jesus Christ on his path for the second coming. Be ready /sci/, I don't want you to be left behind.
>tfw this huge fucking planet is the reason for mass extinctions on planet earth
>tfw every 20k years it is closest to the sun and earth
>tfw every 20k years some fucked up shit happens to earth
Is this fucking planet the key to why life on our planet gets raped?
I bet this fucking thing once observed will be bigger than expected. The only thing we're seeing is a goddamn shadow so far.
The fact that something this large does get that close to our solar system raises the question of potential gravitational changes that could occur within our solar system.
>tfw a few decades from now it's discovered that the planet passes near the red dwarf star Nemesis, which turns out to have four planets orbiting it, one of which has oceans of liquid water on its surface
>Another suggestion is "Thing 1" from Dr. Seuss' Cat in the Hat children's book.David Bowie
Because planets are supposed to have cleared their orbits of other bodies, while dwarf planets have not. This ninth planet may be a gas giant and appears to not have cleared its orbit of other bodies, and so therefore be a dwarf planet about the size of Neptune.
Who's to say that the alien civilization building this dyson sphere is biological. The original occupants of this system could have long ago created a super sentient AI which is now in charge of building this structure for its own expanding power needs. For the machines, this would seem very logical and they could dedicate their entire existence to harvesting resources to build this massive project.
We need to build a massive telescope of our own now to see exactly what the fuck is going on there. This could be our chance to actually confirm the existence of intelligent life outside of Sol.
>/a/ is talking about this
It's inferable, not exactly proven. It's more likely Dark Matter's going to be like Epicycles and Luminiferous Aether, on the plus side it means we're on the edge of a new scientific paradigm for astro and high energy physics.
Damn, that other anon was right.
I should filter any more than 2 consecutive quotation marks.
Anyway I'm calling it now; the newest planet will be called Anita, after Women's Rights Activist Anita Sarkeesian.
>>There are already people claiming this is nibiru or nemesis
>>There are already people saying it's going to collide with earth
eh, I was driving. Thanks for the correction.
You can save yourself some work. Pan STARRS and WISE has already ruled out some spots.
/sp/ here, time for POWER RANKINGS
Assuming it has to be a Greek/Roman God and the Trans-neptunian objects all tend to be named after gods of the dead/underworld:
Legit Cool Tier:
2. Persephone wife of Pluto/Hades
3. Hermes (also a messenger of the underworld, fits with the distance)
4. Erebus, God of Darkness
9999999. Any more Hawaiian or other non western shit.
i propose Jörmungand/Midgárðsormr for it's name.
The name comes from the huge snake in norse mythology that got tossed out into the outer sea by Odin, and now lies coiled around the world, so long it can bite it's own tail, and it dies when the end of all things comes.
>Pluto isn't the main gravitational force of its orbit. Neptune is. Therefore, it can't be a planet.
That's really an arbitrary condition some guys in a room somewhere came up with to get the results they wanted.
Knowing that it's to be crowd sourced, we'll probably get some retarded meme tier shit like Halo or something.
I really like your idea. It makes absolute sense.
But if it looks like the sane choice won't win, I'll votejack to make it ayy lmao.
Just to be sure, Michael Brown the astrophysicist is this guy.
>Assuming it has to be a Greek/Roman God
Not Greek. The planets have Roman names. Mercury, Venus, Ceres, Mars, Jupiter, Saturn, Neptune, Uranus, and Pluto are the Roman names for Hermes, Aphrodite, Demeter, Ares, Zeus, Cronus, Poseidon, and Hades, respectively.
Nothing too special of a reason. She's the least represented of all of Zeus's (or Jupiter's) siblings, and I like her name. Vesta would be better actually since all of the planets use the Roman names.
If it's [the current year] and we're just now discovering this fairly large body, then I wouldn't be surprised if there are more like it.
Hopefully one of them will have some geothermal action going on or something else that's cool.
What are you, a fag?
Here, have the song sung in space.

Name it Lucifer, like the "failed antimatter star" depicted in Yukinobu Hoshino's "2001 nights"
It sure as fuck wasn't Satan in the original story. It's just a random snake there.
The bible is just a bunch of loosely connected stories.
You have god make Adam and Eve as a couple.
Then you have a similar story with different pacing, where Eve is made from Adam's rib.
Fun fact: In Genesys the entire universe is filled with water and "heaven" is a fortification that divides the water on earth from the water outside of earth.
And there's that one story where a king became best bros with a guy who's wife he almost raped because he was told she was his sister. He apologized when he found out that she was his wife.
Yes, raping someone's sister is apparently completely okay.
It's just that Satan is portrayed as a serpent elsewhere in the Bible, so it's assumed by most Christians that he was the snake that fooled Eve in the Garden.
>It's just that Satan is portrayed as a serpent elsewhere in the Bible, so it's assumed by most Christians that he was the snake that fooled Eve in the Garden.
I feel like this is why I started questioning my beliefs when I was 9 or 10. I grew up going to a Catholic school, which wasn't so bad because my other options were pretty awful schools, and boy did I get confused after a while. I was hardcore into religion but then I started questioning things because nothing added up to me or made sense. Then I'd have history class and religion class on the same day and.. you get the picture.
I wonder what happened in that period. In that one little period I could've changed course and been one of those people who were still religious but just because they were told to be, and I'd probably be on a different path in life.
I got confused when I first got exposed to American media and shit like the holy grail or the lance of longinus or the claim that Neon Genesis Evangelion supposedly has christian symbolism.
Took me a while to understand that there's actually a pop culture version of christianity that's completely unrelated to the contents of the bible.
In school we had religion lessons, where we read the bible and talked about the historical content as well as symbolism of the book. We also looked at other religions occasionally.
