Planet V is a hypothetical terrestrial planet that some thought may have existed to explain the "Late Heavy Bombardment" ~4.1 billion years ago. The hypothesis tries to explain how most of the Asteroid Belt was depleted to cause the LHB in the Inner Solar System. The scenarios they tested worked best with a 0.25 Mars massed object when orbited within 1.8 to 1.9 AU. It was thought to also have collided with Mars, forming the Borealis Basin. Later research by (Brasser and Mordbidelli, 2011) tried to refine the theory, but the simulations they recorded didn't match with what was observed with populations of Earth-Venus and Earth-Mars asteroids. Therefore it is likely this planet didn't exist and that alternate explanations for the LHB (Such as the 5th Giant) are more plausible. The sources are in the video description if you are interested in reading more.
I want to see a video on Theia, starting it in Earth's L4 or L5 point and seeing it it ends up getting disrupted enough to collide with Earth, or if something else happens to it
I dont think it was this planet, this giant was way larger than earth and much so for mars, if mars collided with this planet mars wouldn’t exist, it’d be part of the 5th giant
@@PersonyPerson If Mars was ejected from the solar system, it may become a rogue planet, and if captured by another star, it may become an exoplanet This also happens with the 5th Giant if it gets ejected from the solar system
Mars: I’m gonna go get some fast food for you all! *Hasn’t came back in 3B years* What happened was: Mars: *peacefully driving* *pop* Mars: WHOOOOOOO *CRASH*
I'm glad someone is doing something with Universe Sandbox other than hitting planets with other planets and stuff at lightspeed (and other velocities). Watching these simulations makes you appreciate how different our Solar system could have been... indeed how different it may have been before we came along and started peering skyward. Just because we have the planets we do in the order they are in, doesn't mean to say it's always been like that, whatever we might like to believe!

Nice video! ;)
Planet V has to be all asteroids in the asteroid belt combined except for 1 asteroid, that one asteroid forming the asteroid belt. It could also be an ejected moon of a planet, like saturn, colliding with the asteroid belt. Big collision pulled some parts of it, probably Ceres today, but Vesta, Pallas and Ceres combined 4 billion years ago.
i like how earth almost could've lost all it's life and how mars for sure lost life on it's planet. It's how a tiny difference in a balance litteraly disturbs everything.
Same so for Venus! Their water cycle went over a certain threshold that once passed will lead to an unstoppable runaway greenhouse gas effect and engulf it in flames, which it did.
My only gripe with this hypothesis is that Mars would have ejected such a body as close to it as it is hundreds of millions of years before the LHB happened, so there's no conceivable way for this object to still be orbiting this close to Mars at this point in the Solar System's history. The migration of Uranus and Neptune and the ejection of the 5th Giant serves as a much better explanation. Also, I'm not sure what computer you have, but I doubt I could run a Universe Sandbox simulation at 1k years/second. I'd run these myself if I could.
Agreed, but the theory is not completely outlandish and does have some base to it, so it at least deserves to be mentioned. The processor used is an Intel i5-9600K. The simulations are recorded at 250 years per second. It is the recording that is sped up, so it produces the same effect without destroying the simulation with inconsistent speeds.
@@PersonyPerson It's certainly not the least likely proposition, and of course it's fun to experiment with different scenarios to see what happens. But from what I can see, Neptune, 5th Giant and to a lesser extent Uranus migrating seem to cause significantly more disturbance to the Kuiper Belt and bring back a lot more material into the inner Solar System than a small dwarf planet-mass object in the Asteroid Belt. Also, Earth probably got its water from the influx of comets during the LHB, and there's not really anywhere else for it to have gotten it from considering it formed inside of the snow line. I have an 8th gen i5 processor, so not too far away from yours. When I tried running a simulation of the Solar System at 100 years/second, it maxed out at 20, although that might also be affected by the asteroid belts in the default simulation. I might be able to get 50 out of a simulation with just the 9-11 objects, but that's still not really fast enough to simulate a long-term migration. When I can be bothered to look up all the exact orbital properties of the planets, I'll make a Solar System template with just the 8 planets and see how high I can crank it. I used to have one but it got nuked in the awful new surface grid updates. Now that I've seen these my interest is perked and I really want to run simulations with these settings a few hundred times to see what US has to say about the Nice Model, and if any bizarre or unexpected outcomes are reached. I'm aware it doesn't have the most accurate mechanics, especially at high speeds but they work for the majority of scenarios.
The Theia collision occurred roughly 300 million years before when simulation started. This is set on the onset of the "Late Heavy Bombardment", ~4.1 billion years ago. There are links to the sources of the information in the description if you are interested. May do one involving Theia in the future.
Ok, so I’ve got a question or two and really they are more clarification questions than anything. 1) So this simulation starts about 4.1 billion yrs ago when the LHB is hypothesized as to when it started? Concerning the 5th giant, how in the heck did it get into such an elongated orbit?? I mean at one point it looks like it had a 20k yr orbit?!?! Then it comes down to a relative Jupiter length orbit?? 3) How did Mars end up where Neptune is. I consider myself a heavily decent amateur astronomer but this seems over my head:)…One thing concerning 5th Giant, it seems that while ‘it’s’ orbiting the Sun, it’s ORBIT is orbiting the Sun as well…
10:23 oh hell no after trying to calm myself that the gas giants orbits will settle down after their orbits gets so eccentric and close to eachother the fifth giant just crossed the inner system and non of the terrestrial planets get flung expect for mars that get even way far This just went too far
Planetary collisions are actually really rare. They usually happen if bodies share orbits for a long period of time (in the realms of millions of years). Given the relatively short timescale of the simulations and the consistent changes in the planet's orbits, collisions are not expected. The closest to a collision in these videos so far was on the "What if the 5th Giant was twice the size" video, where the that and Saturn had a very close encounter, and that was because they essentially shared the same orbit.
@@PersonyPerson I want to explain to you why the 5th gas giant got tossed out of the system is because it got too close to Jupiter, and Jupiter flung it away. That’s all the information that I can explain.
Planet V is not the same as Vulcan. They are different theories in where there is no evidence to support the existence of Vulcan. See en.wikipedia.org/wiki/Planet_V, and then en.wikipedia.org/wiki/Vulcan_(hypothetical_planet). Maybe read the sources in the description too if you are interested.

Actually Planet V may collide with Mars in ancient time cause a havoc . This impact call Borealis Impacts idk but actually make sense

@@DanksterPaws he means the red one
17:07 How did Mars come back then?
In this simulation, it didn't. That is the consequence of what could occur if the 5th Giant stays in the Inner Solar System for too long.
@@PersonyPerson If Mars was ejected from the solar system, it may become a rogue planet, and if captured by another star, it may become an exoplanet
