Where Is Planet Nine?

People have always been dreaming of conquering other galaxies and exploring space far away from our home. But the thing is that there are enough enigmas in our own Milky Way galaxy! Even better, there is one right inside our Solar System! This mystery is lurking somewhere on the outskirts of the planetary system, puzzling astronomers to no end.

Once upon a time, scientists noticed that something bizarre and inexplicable was causing chaos out there, in space. A mysterious celestial body was influencing the orbits of six smaller object in Kuiper Belt, far, far away from our home planet. This something got the name of "Planet Nine"...

SUMMARY:
- The thing is massive: more than 10 times bigger than Earth and around 5,000 times as large as Pluto!
- Ice giants aren't as massive as gas giants but have a similar atmosphere.
- We used to believe that Neptune is the furthest planet from the Sun. But now, it may turn out that Planet Nine is the champion, being 20 times further away from the center of the Solar System than Neptune!
- If you lived on Planet Nine, your year would last 10,000 to 20,000 Earth's years!
- Until scientists see Planet Nine with their own eyes, they can't say for sure that it exists. But the evidence they have is quite solid.
- Scientists are looking for the planet using infrared equipment. If Planet Nine does exist, it's supposed to leak infrared radiation.
- But then, what if Planet Nine isn't a planet at all? The idea, which first appeared in 2019, suggests that the object that has created all this hullabaloo, might be... a black hole!
- But even if this guess is correct, you have nothing to worry about: Earth isn't in danger. Primordial black holes are too small and weak to cause any serious harm to our planetary system.
- A primordial black hole would explain why hypothetical Planet Nine can't be seen and doesn't produce infrared radiation.
- But one of the main reasons why astronomers would be ecstatic should Planet Nine turn out to be a primordial black hole is the mystery of dark matter!
- Primordial black holes could be the very dark matter astronomers are searching for! Or at least, a kind of dark matter named MACHOs (which stands for massive compact halo objects).

Guys, do you like space movies? Which is your favorite one? 🌟

[stillkickin]

In my heart, Pluto will always be the ninth planet.

Neptune: They called me gassy 😭

Planet nine: You think I feel any better

[JamesLandon]

When Pluto was still a planet, this theory was called, "Planet X"

I love learning about space, videos make it so interesting

Bright side: "where is planet 9?"
Pluto: *bruh*

[mrxklash]

I’ll be 73 before I know true facts about planet nine.

[Cxlors]

To the small ammount of people or anyone reading this, I deeply hope you have a great life and I wish you luck, you are loved and you will get rich, if you ever feel upset just know there are people there for you.

Me, an intellectual:

So, the three criteria of the IAU for a full-sized planet are:
1) It is in orbit around the Sun.
2) It has sufficient mass to assume hydrostatic equilibrium (a nearly round shape).
3) It has “cleared the neighborhood” around its orbit.

Pluto got disqualified for not 'clearing the neighborhood' as it spends @90% of it's orbit in the Kuiper Belt. For 20 yr segments it is not in the Kuiper Belt, and is actually closer to the sun than Neptune, so thus is in a clear neighborhood.

Ceres was disqualified for being in the Asteroid Belt, same reason, not a clear neighborhood.

If the Kuiper Belt disqualified Pluto, then how would Planet 9 (Planet X) not be disqualified for the same requirement?
If there is a Planet 9 (X) it couldn't be in the Kuiper Belt, it would fail Criteria 3.

Beyond the Kuiper Belt is the Oort Cloud, a 3 dimensional cloud of debris. How would anything in the Oort Cloud be capable of “clearing the neighborhood” around its orbit? This is assuming the Oort cloud is considered within the Sun's Heliosphere, which is not certain. Some models have the area between the Kuiper Belt and the Oort Cloud as interstellar space. Not sure you could define an entity beyond a star's heliosphere and in interstellar space as a planet.

Simple logic and the IAU definition disqualify almost any chance that there is a Planet 9 (X)

What if that is a black hole, massive dark matter formation (MACHO) or a wormhole?

Why do I get the feeling that I've seen a million videos about planet 9.... 🤔
