[poll] what is the 9th planet in the solar system

just bored and i wanna know what nuf thinks
im still firm on the fact that pluto is a planet even though it was declassified in 2006 aka a year after i was born

 

Pluto is a dwarf planet in the Kuiper belt, a ring of bodies beyond the orbit of Neptune. It was the first Kuiper belt object to be discovered and is the largest known plutoid.

 

Pluto; king of the plutoids

 

So far in our solar system there's only 8 planet, pluto orbit around the sun is chaotic so it doesn't count as a planet in our solar system

 

i still want pluto to be a planet

 

There is no ninth planet in our system.

 

Hmm, I thought Eris is larger than pluto?

The story of pluto is actually similar as asteroid Ceres:
One day in 1801, a scientist found a celestial object between Mars and Jupiter. They called it "Ceres" and dubbed it as the fifth planet (after Mars). Shortly after, in that area, they found another one (Pallas), and another one (Juno), and another one (Vesta).

Then, a scientists went "WTF, I think this area between Mars and Jupiter just contains a lot bunch of rocks! Rather than making kids suffer remembering all of these bunch, let's just call them asteroids!". Then, they are all degraded to asteroids and the term asteroid belt were born.

As for Pluto, one day in 1930, a group of scientists found a celestial body after Neptune. They called it "Pluto" and dubbed it as the ninth planet (after Neptune). Now because Pluto is far away and limited technology at that time, it was hard to find another object similar to it. However as technology progress, they found another one (Albion), and another one (Haumea), and another one (Makemake), and many more.

Then, a scientists went "WTF, I think this area after Neptune just contains a lot bunch of rocks! Rather than making kids suffer remembering all of these bunch, let's just call them Kuiper Belt Objects!". Then, they are all degraded to Kuiper belt objects and the term Kuiper belt were born.

...Or so I would want to say, but just kidding. They actually said "OK, if there are no rocks larger than Pluto in that area, then Pluto can stay as a Planet".

Then they found Eris, which is 27% larger than Pluto.

So, bye bye Pluto.

And if you want Pluto as a planet, then Ceres should be a planet too T_T. (Equality!!!)

 

Pluto is a shota planet

 

I still count pluto as a planet.
Too old to not consider it one.

 

Isn't ninth planet is Nibiru with reptiloids?

 

*Cat girl heaven you mean.

 

I am a fan of the ninth planet theory, Though I did see an article where they hypothisized that the gravitational effects caused by the hypothetical ninth planet could be caused by a primordial mini black hole...

 

If you want to reclass Pluto as a planet, the the ninth planet in our solar system is Neptune.

 

IIRC, Pluto was declassified as a plant because since it's discovery in the 1800s, it hadn't completed a full revolution around the sun even once.

 

It was really declassified in 2006? I have some memory of discussing it in my Astronomy class in 2005, but maybe it was just rumors that it was going to be declassified... I wonder if I still have my presentation I did on the Kuiper Belt... probably... *too tired to look for it now*

 

Wasn't there that planet with the ridiculous orbit that takes 557 years to complete 1 orbit around the sun?
I don't remember its official name but I do recall people giving it the nickname Eris

 

I looked it up, and supposedly it's because Pluto has not cleared its orbit of other bodies. Whereas other planets turn nearby objects into moons/satellites, Pluto orbits near the Kuiper Belt. And if Pluto were to be a planet, then so would multiple objects in the Kuiper Belt. Therefore, astronomers decided one of the criteria for an object to be a planet is to clear its orbit.

PS: My answer no doubt has inaccuracies - I am neither well-versed nor invested in astronomy. But you get the gist, person-who-is-about-to-criticize-me.
