Where Is Planet Nine?

  • 🎬 Video
  • ℹ️ Description

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"...

- 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).

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

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

What regular people think when they discover “Fatty”: wow we do have a 9th planet!
People that still think Pluto is a planet: well we have 10 planet in our solar system noice

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

In the many simulations that have been tested it always works best when adding a big planet, a 'Super Earth' to be specific. The black hole theory is interesting tho and it has reason to be investigated.

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

Author — Perpetual Bystander


The fact that the 1800s and 1900s also had a rocket ship makes my jaw drop



i learn more by watching this than going to school, also its entertaining.

I like how bright side says wait wait wait does it mean it's going to swallow us and all the solar system that makes me laugh 😹😹😹😹

Author — Allen Dim


Wow this sounds like a job for Gravity Falls to look into🤣🤣🤣🤣

Bright side: hmm do I pick a name, planet 9 a more serious name... Or a silly name,

Bright side: ah yes fatty it is!

Astronomy, gives us so many goosebumps.

What really scares me is the thought of it being a black hole…

Veritasium : Makes video on planet nine
Bright Side : Let's do a remake, but let's keep the thumbnail same

YES! I got so excited back then, when I heard about the primordial black hole theory in general and in our solar system specifically. Ever since 20 years ago, when I heard about 'Plante X' for the first time (back then, Pluto was still no. 9) and heard about the specifics from one of my science classes teachers (who was really interested in astronomy and fired my childhood obsession with it), I was wondering if it couldn't be something like a small or a baby black hole.
So, yeah, I'm totally team primordial black hole!

ah yes, the planet that near collided with earth in smallville
