Is there a ninth planet out there?

There's plenty of planets out there
theres probably at least a dozen more substantial dwarf planets in the kuiper belt and maybe many more out in the Oort cloud floating around and perhaps a couple mars or earth sized bodies
its not really surprising
a lot of these bodies have very weak albedo and super long elliptical orbits
makes them hard to spot

I don't care what anyone says, if it CAN be a planet, then it can be a planet AGAIN.
PLANET, PLANET, PLANET.
>>7961838
This is insanely old news.
They still need to actually find it, though.
>>7961838
>Is there a ninth planet out there?
Maybe.

>I don't care what anyone says, if it CAN be a planet, then it can be a planet AGAIN.
Yes, why bother with rigorous categories when we could just appeal to tradition. That's obviously far more rational, and not biased at all by people's view that a dwarf planet is somehow "lesser" than a "real" planet.

Pluto can't be a planet, the only reason it was thought to be one was due to how little we knew about the solar system even 20 years ago.
>>7962541
WISE says hi.
>>7961924
It is unlikely there are Mars/Earth sized planets that far out unless they were ejected from the inner solar system like Planet Nine is believed to have been.
>>7961838
There's more out there. Do the exercise to find out why detection is so difficult.
The real question is when are we sending a probe there?
It doesn't matter if there's a ninth or not, we'll just be going down one after I destroy Uranus

I wonder if you understand the irony of your behavior, and no I am not the anon you are shitposting with.
>>7962552
Why can't it be a planet? That bit about clearing the neighbourhood is pretty arbitrary, as discriminates against planets surrounded by lots of asteroids.
So what if we have hundreds of planets in the solar system, we have billions of stars but we don't say that most stars aren't actually stars.
>>7963472
clearing the neighbourhood has a clear definition based on distinct characteristics
>a planet (as so defined) will have "cleared the neighbourhood" of its own orbital zone, meaning it has become gravitationally dominant, and there are no other bodies of comparable size other than its own satellites or those otherwise under its gravitational influence
demanding a dwarf planet be considered a planet is clinging to ignorance, you might as well be arguing the sun revolves around the earth
>>7963525
But surely that has as much to do with the neighbourhood as the planet itself. If you put Mercury near Jupiter would it suddenly not be a planet?
>>7963472
But we do classify stars into different types, just as we now classify planets into different types.
>>7963536
Yes.
Kuiper belt objects like Pluto are dominated by Neptune, Mercury would be under the influence of Jupiters gravity and be a dwarf planet (assuming it had an resonate orbit that kept it from being ejected).
>>7963576
>But it wouldn't be any different to what it is now.
Do you not comprehend what it means to be gravitationally dominated by a larger planet?
>>7963581
Yes, but that doesn't have anything to do with the body itself. Clearing the neighbour is arbitrary.
>>7963576
Why should Titan, Europa, Io etc. be moons of Jupiter just because of where they are?
>>7963588
>that doesn't have anything to do with the body itself
Actually it does.
An arbitrary qualifier would be the color, not the orbital mechanics.
>>7963602
How is clearing the neighbourhood defined anyway?
>>7963576
>We categorise them, but don't say they're not stars.
Just like Pluto is a planet? Just because it has the word "dwarf" before the word "planet" doesn't mean it isn't a planet.
>>7963536
Jupiter has moons bigger than Mercury. The definition may seem arbitrary to you, but clearing the neighborhood is just a temporary criterion until we can clean this mess up. Just so everyone is on the same page I suppose
>>7963743
Honestly the real reason why they made up those contrived rules is simply to keep the solar system neat. The Kuiper Belt looked like it was about to cough up 50 more planets, would have been a nightmare for teachers.

Unfortunately, this is not correct.
A dwarf hippo is still a hippo.
A dwarf person is still a person.
Even a dwarf star is still a star.
But the IAU, in their infinite wisdom, chose the word "dwarf planet" to describe something they define as *not* a planet.
It's truly retarded.
>>7964131
>Even a dwarf star is still a star.
Not all of them.

Dwarf animals are genetic mutations, it is intellectually dishonest to make that comparison.

I liked when pluto was a planet and the mystery planet was called Planet X and it sounded a lot cooler.
>>7964530

that's nice honey
>>7964530
I like when people don't hold up ignorance like a badge of honor.
>>7964131
I'm not really sure why this is a big deal to you. We label things to produce useful categories for discussion. Sometimes the categorisation works in different ways for different types of things.
>>7964536
>pluto is still a planet you retard
It's really not. This is all publicly available information.
Serious question though, in discussions I often find myself talking about "rocky planets, dwarfs or moons heavy enough to be round" (ie. things you could stand on). Is there a decent label to group all those things together?
>>7964917

>There's plenty of planets out there
This is what you people should care about. I'm not saying we should focus on the planets in our solar system, just that to have this extreme focus on the number of planets in our solar system is what caused people to give a shit about Pluto being demoted.
It also makes it easy to ignore the other things in our solar system. There are people who don't even care about the recent exploration of Pluto, simply because it was demoted. The entire population of Earth could fit on the moon..
>>7963061
>by size and distance from me
I don't understand how the Earth is ~20000km from anyone
>>7963472
>That bit about clearing the neighbourhood is pretty arbitrary
How is it any more arbitrary that any other distinction between celestial objects?
It shows that it is the dominant gravitational body in that area, as a planet should be.
>>7963581
Could I argue that a prisoner isn't actually a prisoner because it isn't an intrinsic of his body, but an "arbitrary" artefact of his current position in prison?
Being a planet is about more than just what the thing is, but how it fits into the solar system. This is more important than you seem to think, since you can't just move Mercury next to Jupiter - the solar system formed in a particular way and the definition of a planet reflects these dynamics.
fuck you fags
even the moon is a planet
if it orbited the sun directly we would call that shit planet luna
fuck orbital neighborhood and this other crap
I have my own personal definition
a planet is really anything big enough to achieve hydrostatic equilibrium that isnt a star

Thank you Based alien

>It also makes it easy to ignore the other things in our solar system.
The entire reason 'dwarf planet' is a thing is because we learned there is a hell of a lot of other things in our solar system.
