Pluto is still there, unchanged, orbiting like it has been. Stars, planets, and dwarf planets aren't "real". They're just categories of bodies that have a certain set of features in common with each other, and the lines between these categories are extremely fuzzy and debatable. They're only there as a means to help scientists organize their knowledge about the universe. But they're artificial; nature doesn't care.

It was also the only probe to investigate an object that had not yet been discovered at the time of its launch. After its flyby of the Pluto system, New Horizons did a flyby of Arrakoth (previously known as Ultima Thule), an object in the Kuiper belt that was discovered with Hubble after New Horizons was launched. Granted, they were using Hubble specifically to try to find a new target for New Horizons. It's not like Ultima Thule was discovered coincidentally and NASA was like "hell we already got a probe out there, let's make a detour." It was a contrived series of events, but still a neat factoid.

The cautionary tale of "Vulcan" should be mentioned with this however. The idea that math was so precise that it could be used to predict a planet due to perturbations within a planets orbit, it convinced a great many scientists that there was in fact a planet within the orbit of Mercury. Of course we now know there is no planet "Vulcan" (within our solar system at least!) and Mercury's orbit was explained through Einstein's determination of how gravity truly works within space-time.

"truly" Not your finest choice of words. ;) We know that relativity cannot be a complete description because of quantum and the problems with trying to combine the two. "More accurate" would be a better phrase there. It's important to realize that the mathematical quantities we use in our models don't necessarily correspond to some kind of fundamental physical property. The notion of "force" that was so fundamental to Newtonian mechanics is now virtually discarded in the more updated theories; other concepts have taken its place as more fundamental and central. And getting beyond Newtonian mechanics required introducing completely new ways of understanding how objects interact and discarding ideas that we thought we fundamental. We have no idea what new concepts the next more accurate model will introduce or what old mainstays it will discard. Really disappointing that Astrum didn't cover Vulcan.

And it would give our solar system the mini-Neptune/super-Earth that seems so common in other exoplanet systems.
One of the coolest ideas (and most terrifying, I guess) I have heard about planet 9 is that it is not a planet that we haven't observed, but rather a primordial black hole. These are very small black holes that are predicted to possibly exist with our current understanding of astrophysics. Crazy thing is, if they do exist, they would be completely undetectable due to only having diameters in the range of an average apple or human fist... It probably isn't a black hole, but again, we do not know if these exist or not.

It wouldn't be impossible to detect, just STUPIDLY difficult. You'd be looking for a trail of very small microlensing events happening at a speed and trajectory that would suggest that the object causing them would be gravitationally bound to the solar system. Ideally this would include a microlensing event in front of one or more trans-Neptunian objects, which would confirm that the object causing them is within the solar system..

The speed of the sun likely impacted the orbit of the planets and moved them to one side. However, the Planet nine could cause to accelerate that process. If the Planet nice doesn't exist or is very small, it challenges the theory of general relativity a lot. I think, gravity depends on gravitons that relatively move planets to a direction depending on the speed of the sun, rather depending on an uniform curvature of space which doesn't change with the speed.
A small correction. The Babylonians did not determine which objects moved around the Sun. They determined which "stars" were moving irregularly. It was quite some time before people figured out that they were planets, and not just weird stars. It's actually quite easy to look at the sky every night and see every star in the same place as every other night except for a handful.

That mass of so-called planet nine could be even less dense then some puffy planets, perhaps being a slowly pulsating cloud hardly detectable, not being fallen into itself to had built actual mass as we would define, being to cold to start to stick together, gravity not always being the deepest "force" but that's me speculating. So some gravitational effects would be discoverable in more precision but any visit of that object could turn out similar like the japanese probe (named with five letters) in 1991 or 1992 trespassing a Kordylewski cloud whilst being unable to collect samples of dust. But i don't want to de-fascinate the topic with having added this not so relateable thought. does asteroids (at) home support the topic?

Pluto and Uranus I think do cross orbits every once in awhile . If planet 9 is real the normal planets are sort of in random position every time planet 9 comes back around . This could really screw things up

@@jondoc7525 Space is big. Any comets that were disturbed would first have to travel a few million years before they reached the inner solar system. Even if they did, the chance of one impacting Earth is quite low. As for Planet 9, it is too far away to affect anything besides the orbits of TNOs. I don't think many people here understand that gravity gets exponentially weaker with distance. Sagittarius A, the black hole at the center of the Milky Way has a mass of 4 million suns, yet the dominant object in our Solar System is the Sun. Why? Because the Sun is 1 AU away, while Sagittarius A is 1.64e9 AU away.
Extra fun fact: Since Neptune was discovered with math, some scientists tried to discover a planet closer to the sun than Mercury, called Vulcan. There were even lots of misattributed sightings of Vulcan. The Newtonian math supposedly called for the new planet, but it wasn't accurate. When we got Einstein's Relativity, we were able to solve the math without the need for Vulcan.

For people who are interested, there's a great video by Zepherus on the topic
Yes please!! We need the tutorial!!
Thank you for covering this in such a thorough manner! I am constantly hungering for new information on a variety of topics, and news of Planet X has always made my brain itch in such a pleasant manner. Please keep up the great work! 🖤🐻🧙🏻♂️
Zooniverse would be interesting. You forgot to mention that many stars close to Sol are in high relative motion to it, including dozens of red dwarf stars plus binary and triplet stars (Alpha Centauri is a triplet star, which is obvious, but suppose two or more red dwarfs are orbiting each other and so on). Plus all the millions of Kuiper Belt icy asteriod sized objects beyond Neptune (which Pluto is one, Eris is another) This adds to the complications of finding planet X.
Just wanted to point out at 7:30 you said that we still haven't discovered Planet X to account for these oddities in the ice giant's orbits; these irregularities were solved when voyager 1 & 2 came along and gave us more accurate data on the planet's mass which showed that the orbits were completely normal, our data was what was wrong. Love the video though

what he was mentioning there was before the discovery of Neptune, also this theory is talking about the orbits of TNO’s
I remember watching videos on KZread when I was maybe 10 or 11, with titles like "Planet X is coming". Of course, I didn't fully understand what they meant, so I thought it was like a roaming planet that scientists found that was coming to swallow the Earth lol. It's nice that I know the full story of its legend so many years later.

Passion makes a huge difference
I'd love to see more information about all the brown dwarfs and the like which the search for Planet X has incidentally found throughout their search. How many have they found? How far away are these places? Are they a part of their own solar systems or are they far flung exclaves of a much larger star system sort of like how Proxima Centurai is to the Alpha Centurai star system? Would any of these celestial objects be both close enough and interesting enough to potentially send some form of probe to in the next century? There's a lot of different questions that the unintended finding of these objects bring up and it'd be great to get a run down of them.

I remember the German version of the mnemonic from my childhood :) "Mein Vater erklärt mir jeden Samstag unsere neun Planeten" I never thought about what it might be in other languages
I have found the counter arguments (if you can even call them some of them "arguments") quite unconvincing. Firstly, it is not "easy" to spot and track even largish objects at distances of 500+ AUs, especially when you don't know *where* on their orbital path they happen to be. It's a monumentally large amount of sky to sift through. Planet X could be as far as 1000 AUs (I'm not sure where your lower figures come from; perhaps more recent data) Secondly, the argument "then why haven't you found it yet" is not an argument, for reasons laid out in my first point. This would be like arguing back in the day that "Uranus and Neptune don't exist because why haven't you found them yet?" It would be more sensible to say "I will reserve judgement until an affective search method has either discovered or ruled out (to a convincing degree) planet 9". *Certainty based on a lack of evidence is utterly unscientific* I believe the modelling and tracking data of perturbed KBOs quite convincing; whether it's 99% convincing? In any case, the counter arguments *are* weak.

Mate.. your first "unconvincing" argument also works against the 14 objects that were discovered as "bunched". If you claim it's so hard to track those objects, then it applies to those 14 as well. What is the argument then that this planet exists?

I'd like the research to be bold for this is something that has an equation to look at and maybe something new to ad in a different way of planning cosmology.
The reason Planet Nine has not been observed, yet, is a combination of factors: the background it is in front of from our perspective, and the possibility that it is at or near the farthest point of its orbit and is therefore moving so slowly across our sky that some background objects are moving faster than it is, thus keeping it mistaken for a background object.

@@DAGATHire I watched the video. It didn't corroborate what I am saying above. That's why I posted what I did. I am convinced that Planet 9 (or Tove Ra'ah, as I would name it) is out there, but I am also fairly well convinced that it will not be found by our usual methods. Instead, I think that an unplanned gravitational interaction (be that with a deep space probe or, for example, a very large comet) will betray the planet's presence.
8:07 I've also seen presentation of a paper (I think it was on SETI Seminars) that showed that this crown shape can be caused _without_ another massive planet. Rather, the apogee end of these highly eccentric orbits will attract each other. So what we need to form the observed crown-shaped structure is a few more of those, which (due to observation bias -- astronomers spot the ones that are currently near perigee) most likely exist. The dwarf planet spends most of its time in the extended lobe near the apogee, since it moves slower there and it is larger. This means planets hanging out there will attract each other and torque the orbits as shown. It is 20 other dwarf planets hanging out at the far end of the orbit, not a single massive body, that causes the observed clustering. Now the math shows that this effect _does happen_ . So why don't the Planet 9 people include it in their calculations and conclude that 1 large body or _n_ small bodies or some mixture of medium-sized bodies in this kind of extended orbit would do the trick?

Because the headline reads better. Let’s be honest “Mysterious Planet X Plays Havoc With Our Home”, will attract way more eyeballs than “20 Small Rocks Exist, Solar System Finally Noticed”. My one major gripe with scientific reporting is that the journalists and papers still attempt to inject sexy and/or exciting into news that really doesn’t need the help. As a result, people expect the big headlines and straight answers, science isn’t really allowed to just be awesome as itself.
I want to see an Ed Wood style movie on Planet X... Planet 9 from Outer Space! It orbits in the dark... but soon it will come to the light!

You skipped a big part of the mathematical planetary prediction that took place immediately following the discovery of Neptune- Vulcan. Because of the models used in the prediction of an ice giant disturbing orbits in the outer solar system, another prediction was made after noticing that Mercury wasn't actually behaving correctly either. It was assumed that there were another planet inside of Mercury's orbit. Go check it out, it's fascinating.

I believe Planet X does exist, and here's why: When models were being made to show how our solar system ended up the way it is, the only way the researchers could get our current solar system as an outcome is if a planet bigger than Earth but smaller than Neptune got ejected as Jupiter moved through our solar system in the early days. My theory is that that ejected planet wasn't fully ejected, but rather thrown out to the farthest reaches of our solar system.

I think for Planet 9 to exist it would be insanely lucky to be even found especially with say its orbit being a very long one. Whoever finds it will definitely remembered and go down in history but good luck if its ever found. Everyone putting in effort for over 100 years we could find it if its there
