Massive Planet Disturbed the Solar System Long Time Ago

[@charliemintz]

I remember looking at diagrams of the solar system's formation in the TIMElife books back in the 1980s; when it was proposed that the planets were formed when a star flew by the sun and pulled matter out of the sun that condensed into the planets. We now know this was not the case, but how strange that the fly by idea has been revived!

[@tsbrownie]

There is a known planet 9. Pluto, you will always be a planet to me.

[@markcash2]

***This is for YouYube commenters, not Anton.*** A lot of other comments are based on a certain segment of KZbin viewers not understanding statistics. It is not that there is a one percent chance that a flyby caused the eccentricities in our orbits and inclinations, but that out of all possible flybys, about one percent of them would cause similar results to what we see today. The likelihood that a flyby actually caused the eccentricities is much higher, or at least far more likely, than the planet 9 theory. So much more likely that we must discard the previous hypothesis and work on the assumption that a flyby did occur (not proven, just that the model works better than the planet 9 model). Right now the problem is to computer model the orbits backwards in time to find the time when the flyby occurred. At that point we can then start modeling the size, density, and vector of this rogue planet.

[@Dustin_Bins]

Interesting, thank you for this information!

[@Davivd2]

Even with reverse orbit modeling of known objects is still unlikely to find the smoking gun. There is so much out there that we can't even detect. James Webb telescope just reinforced that point by how much it was able to detect. We will be lucky to ever get a definitive answer on this matter.

[@spvillano]

Likely, any giant of any sort flyby would cause ejections, at a minimum, minor planets and smaller, as well as were it to penetrate the Oort and Kuiper belt, some inner solar system bombardments and a fair number of comets. Again, back dating via simulation and calculating back would find the time frame and impacts that correspond to that time frame, helping to confirm it. Sounds intriguing, but it'll take a hell of a lot of supercomputer time to calculate everything, as well as protracted, repeated runs to replicate the results just for any proper paper to be written. Suffice it to say, if not yet fully buying in, I'm sure renting it for now. Because, that beats running with the notion of a stealth gas giant flitting about that defeats multiple IR surveys looking for just such an object. And the only other candidate being a close pass by another star, which somehow didn't perturb the planets all that much and what little it did, variably in ways that gravitationally makes zero sense. Unless someone has a special inverse square law exception card they want to reveal to the universe. I suspect we'll see proton decay before anyone manages to produce that card. ;)

[@mikecaster4612]

I would start looking (time reference) for the planet sweeping through at about the time of earths "Early bombardment" when a lot of material was being disturbed.

[@michaelstiller2282]

Huge assumption in that, "work the computer model backward in time, to find when the flyby occurred." Basically predicting a condition which was present at the time prior to the event. That kind of science don't age well.

[@danoblue]

We used to think our sun was a rather common star, and our solar system a normal model for other solar systems. Now it looks like every solar system is different due to the dynamics of the area in which it forms and the number of objects which may or may not influence its development. What this means for the development of extraterrestrial life remains to be seen.

[@ThexBorg]

With 400+ rogue planets drifting in the Orion Nebula alone in the field of view the likelihood of a rogue planet flying through the solar system is not that unlikely.

[@fanofentropy2280]

I'm old enough to remember back when Pluto was still considered a planet, we were looking for Planet X. Much cooler name imo.

[@patandthecats5983]

I'm still a proponent of a possible plant 9. If it's orbit is extremely narrow and long it would be nearly impossible to find. We look for planet transition to find them but if the plant is moving more out than across than transition doesn't work as well.

[@richardshansky3040]

Anton, did it have to be just one flyby event? 1-in-100 chances suggest it could have happened several times in the early solar system.

[@stevejohnson3357]

We need to be careful about what we do with our trash, don't we. You can toss a single use bag into the trash and it might eventually make it to the ocean to choke a whale. Likewise, ejecting a planet into the blackness of space could end up damaging someone's home.

[@thomfiel]

It's not surprising that some rogue planet passed through our solar system billions of years ago. It probably happens in other star systems as well. However, I hope that it does not happen again in the near future; such an event would throw Earth's orbit way out, and that would be the end of us.

[@UnfollowYourDreams]

That highly depends on where it enters the solar system.

[@edwardteach3080]

It’s such a delicate balance. Imagine if our planet stood up straight and stopped wobbling suddenly.

The elephant in the room is the tilt of Uranus, just past the orbital plane. That could not have happened without the planet having been disturbed in a flyby long ago. It's hard to imagine another explanation.

[@kulpritblk1578]

There's one way to definitively tell, if there was a large object entering the solar system then each of the planets would be affected differently as the force between objects is proportional to their mass. So if there's a theoretical shift that correlates with a specific mass that's also observed than we can say with certainty that it did happen.

Common sense would say if you're trying to find evidence of a fly-by, you would look at the objects with the highest orbital inclinations. Then try and distinguish if there's a cluster of objects grouped together in the same plain as they would have all been dragged out as the planet left the solar system

[@christophersmith8316]

They threw Pluto out of the planet so they didn't have to use Pluto/Neptune area as where this happened and to neglect pluto's orbit and inclination.

I heard about the Theory that the Gas Giants migrated outwards long ago, maybe a flyby also explains how that happened...

[@Dustin_Bins]

I'm not certain if it's true, but I read that a fifth gas giant has been hypothesized since 2011. Does what Anton is talking about have anything to do with this?

[@gravitonthongs1363]

Nibiru is the name of a hypothetical planet that has been the subject of doomsday theories since the mid-1990s. It's also known as Planet X or Planet Nine. The proposal of a close fly by from a rouge celestial body better explains any speculative evidence supporting Nibiru.

[@terranovarain6570]

​​​@@herbsandflowers8152 the original evidence to suggest nemesis is because of mass extinctions starting 600 million years ago found by lack of marine invertebrates in the fossil record with a periodicity of 27 million years you know how fast and elliptical it would have to be traveling for a orbit of 27 million years that scrapes the oort cloud what are the chances of finding it's exact spot and tracking it long enough to see its ir signature how would we even guess what it's inclination could be not saying it's right but with dark comets like Oumuamua paying us a visit I wouldn't rule it out oort cloud objects would most likely be made of ice methane ice nitrogen they wouldn't tell us even if they knew considering the implications at the very least it appears something has our number in a clockwork fashion maybe a perturbation of the oort cloud by this rogue planet

[@terranovarain6570]

instead of a bombardment that causes a ice age what about one that puts enough methane in the atmosphere to boil the oceans I imagine in that situation the only place marine life would stand a chance would be at the poles

[@adamhe512]

The hypothesis that the inclinations of planets’ orbits in the solar system were caused by the disturbance of A flyby rogue planet or interstellar object seems to be funded on another hypothesis that all the planets had no or little inclinations in the first place when the solar system was born. This latter hypothesis is even harder to justify. Irregularities appear to be the norm of any system if we look into the details of that system

[@SupernovaBoi-wb8rp]

It has to do with the gas giants in the solar system 4.6 billion years ago

Odds do not support reality. Statistics are 'best guess', especially in low probability scenarios. One is less than two, probably. Does that mean two is improbable?

[@cpmf2112]

Why would all planets have exactly the same inclination? I would expect some variation. 🤔

[@gravitonthongs1363]

A good point, but they do deviate mildly.

[@mickimicki5576]

Initial conditions could have included a lot of lumpiness and compositional variation more than enough to be responsible for the ultimate eccentricity distributions

[@Atok595]

Uranus though

[@markmcd2780]

That expectation would seem highly likely given how we are told the planets formed. All those collisions should produce random variations rather than a 'picture-perfect' system with everything lined up. And the 4 gas giants would interact with each other during formation so maybe the giant invader isn't needed.

[@markmcd2780]

I wonder what the confidence is on the timing of such an event. It's about 80,000 years estimated since Scholz's Star brushed by the solar system - a VERY interesting date given the genetic bottleneck of humans from around that time. But as a brown dwarf it qualifies & may have planets of its own - or even left one or some behind... Looking at you, Pluto & other dwarfs... Could perturbations have settled down in that time?

[@douglaswilkinson5700]

Anton stated this happened "20 million years after the solar system formed" which was 4.6 billion years ago. Our Sun & solar system were close to the other stars & their planetary systems at that time.

[@markmcd2780]

@@douglaswilkinson5700 Nobody knows that for sure. It is a figure plucked from an hypothesis to support a conjecture & while the possibility maybe be reasonable the details are, at best, guesstimates to make the maths work. Even the story about us coming from an open cluster is not actual fact but a best guess scenario. Things like the odd elements found on asteroids could be from our journey through stranger space than we have been in for recent epochs. As in, we've been in a void for a while but also transitioning through Local Fluff & are just emerging into a cleaner space recently. I'm just querying whether a known event might also fit the characteristics more recently.

[@markmcd2780]

@@douglaswilkinson5700 Any particular part to which you are referring? Because if a super-Jove at 20AU could do these things so could a much larger object at greater distance. And to be honest I doubt a super-Jovian at such close range would leave the solar system anywhere near to orderly situation we see. But that's just my guesstimate. 20AU is around the orbit of Uranus. Seems to me a mass of (say) 25 Jupiters would create a ripple that would come close to destroying the nascent planetary disk 20M years after formation. (25 as the mid-range of the quoted 2 - 50 Joves, most of which is well in the brown dwarf range) Scholz's Star with a red dwarf & brown dwarf combo wouldn't have to be anywhere near as close as 20AU to have an effect equal or greater than a Jovian passing through the ecliptic. And the timing question remains. There are so many unknowns in this hypothesis the time quoted might easily be orders of magnitude out. A larger mass further out could easily have effects on the system as a whole particularly as we don't know orbital parameters for when it might have occurred. e.g. all planets in orbit close to the encounter would be more affected than those on the far side of the sun. I'm thinking here of the outer planets in long slow orbits which might be more affected as the planet or star approached while the inner planets are more tightly locked into the solar gravity well.

[@michaelstiller2282]

Jupiter and Mercury are the only planets that have an axial tilt that derives from the accretion disk theory. Meaning they are born here in this system. Earth, Mars and Saturn share a common axel tilt, suggesting they were hit or they are not born of this system, and possibly Saturn was the parent rogue brown dwarf star to Earth and Mars. The JWST found thousands of rogue planets, and red dwarf stars in 1 nebula alone. So there are lots of rouge planets and brown dwarf stars roaming around. Ganymede, a moon of Jupiter is the size of a planet. Venus, and Uranus don't even have a spin common to the sun. They could also be captured.

How can a rogue planet, or what ever object, go only 2-7 km/s between Mars and Earth? That is impossible, it should have had a speed of more than about 35 km/s (= sqr(2) times Mars's orbital speed) in order to be able then to escape the Sun's gravitational influence.

Read the research papers Anton used to create this video.

[@aaronperelmuter8433]

What’s impossible is understanding why you think Mars’ orbital velocity has any bearing whatsoever on whether or not a rogue planet could have passed by us at about 2-7km/s. The speed with which Mars is orbiting the sun has nothing at all to do with a rogue planet being able to pass us by. Omuamua (the cigar shaped rock, I know that’s not how it’s spelled) passed through the solar system a few years ago and it DEFINITELY had nowhere near the speed you said, 35km/s. It only had a speed of 23km/s and this was more than sufficient to allow the thing to escape the solar system.
