Good, we have enough planets in Sol as it is.
This actually happens a lot in other star systems.
Lots of the exoplanets we're picking up these days are easy to detect because they are 'Hot Jupiters', basically, a jupiter size planet or larger, but orbiting in a mercury-type orbit.
The reason this is commonly thought to happen, is if there is too much gas, dust and icy material in a system's planetary nebula as it forms, then there's enough material to create a whole bunch of very large gas giants.
But so many super big planets in one system don't play nice, their gravity interacts and usually theres one that will be slightly bigger, that flings the other planets out of the system to become rogue planets, however, that large gas giant also loses a lot of it's orbital momentum from ejecting the other giants, and as a result falls down into a closer orbit to it's star.
A hot Jupiter is usually the sole remaining victor in a game of gravitational bumper cars, worn out and nearly defeated, spiralling into it's star.
...Are you telling me Jupiter is at full power?
Yeah, that is one of the main problems, but in any case, we do now know that Hot Jupiters are very common.
This seems to make sense, if theres a certain critical mass of matter present in the planetary nebulae, and that at every point above that you get these Gas Giant gravity wars, then that's a significant chunk of the spectrum that is in Hot Jupiter territory
When they collide? the gas giants? they usually don't get close enough to. generally it's their gravitational fields shunting each other while they're both flying around on their own orbits.
If two did collide i'd suppose you'd get a very hot and chaotic collission, and either the debri would scatter out into a field belt, or if the larger planet managed to stay more or less together, it'd absorb the mass of the other one.
Anti-jovians pls go.
>yfw Saturn is actually the benevolent one despite its spooky sounds
he just want to pray game
Saturn is the thinking man's planet.
Jupiter is cowtits by comparison.
Saturn is /fit/ and /fa/
Also, doesn't have downs syndrome.
Mars is shit-tier.
Neptune is also an acceptable choice.
What a faggot. When is Jupiter going to stop his bullying? He's already old enough to have matured beyond the "wah wah I'll make everyone else unhappy to feel better about myself" phase! Fucking Jupiter.
>Neptune the shy girl
No need to worry, my children.
Are any of you interested in some developing real estate, by chance?
>Jupiter cruised through the solar system, eating some planets and flinging others out into interstellar space
Why the fuck is this so terrifying?
I guess he couldn't handle the pressure
>There are countless rogue jupiter sized planets just flying through interstellar space that we can't see or detect
What if one's flying towards our solar system right now?
Our Jupiter shall awaken and select a hot-blooded youth from Planet Earth to join it in repelling the invader. Because if the Solar System has to end, it shall only be by Jupiter's hands.
WORLD DESTROYING HEAVYWEIGHT PLANEZOID JUPITER! Debuting on Saturday TV at 10am.
Let's settle this once and for all, boys.
Likely not. That water and subsequent life is probably still the result of comet collisions.
But if Jupiter hadn't cleaned out the inner solar system of those early proto planets before tracking back out to its current orbit, it's likely Earth would never have formed at all
>Jupiter create a mobile suits for Earthlings to fought off Giant Gas Invader
>Because if the Solar System has to end, it shall only be by Jupiter's hands.
>Final boss is Earth v Jupiter in a Student v Mentor fight
FUCKING FUND IT
Saturn(and possibly another gas giant that Jupiter ejected in the process) is most likely the reason Jupiter didn't become a "Hot Jupiter" and sterilize our solar system.
Thank you based Saturn.
>Saturn has a hexagon on its north pole.
>There's a giant beehive in Saturn.
Jupiter plowing through the inner solar system is probably the reason Venus ended up with such a slow rotation period(a Venusian day is longer than a Venusian year) and ended up retrograde, through either interaction with Jupiter's gravity or another planet sized object being hurled at Venus by Jupiter's gravity. Similarly, Jupiter is also probably the reason Thea got launched at Earth, giving us the Moon as a result.
There's also and idea that Mercury was impacted by another similarly sized object early on that blasted off it's crust, leaving only its mantle and iron core behind as Mercury has an abnormally large iron core in comparison to its overall size.
I thought Jupiter was actually supposed to be kind of bro, sucking in asteroids and comets that would otherwise wreak holy hell on the the inner Solar System. Sure, it might chuck a comet at us one day, but hey, no one's perfect.
Judeau literally fucked off to Jupiter with some no named whore who didn't do shit other than look pretty,leaving his sister and friends behind to fight/die in the new war against Char,the guy that wanted to throw a giant rock at the planet his sister was living on.
He realized the truth of UC: it will never get a happy ending because there will always be another Zeon reboot to sell merch if things start looking up.
He took the third option and fucked off to China.
That's the stage afterwards, a Planetary Nebula. Nothing left but cold dead outer planets with no more sunlight as all that's left of the Sun is a White Dwarf. The inner planets are gone.
I thought the projected expansion would destroy the Earth, at least.
And we'll all have to move to colonies in the outer arc... orbiting under the shadow of Jupiter. Oh dear.
Mercury and Venus would be destroyed.
Earth will either be consumed or just rendered a barren rock.
I don't know what will happen to Mars.
The Sun going red giant might also allow bodies like Titan to become habitable.
(All this assumes humanity hasn't developed super technology to shuffle around planets by that point)
We could always move her to orbit her big sister. Might still be warm?
It would be a kind of morbid memory to move around the universe in the frozen remnants of our Earth, as space nomads, once Sol goes upside-down on us.
>It is said that these hoo-muns, they without a home, the impregnable superfortress seen only in the skies when they arrive to trade in a galaxy, was once the birth planet of their all of their civilizations.
>Really? Ew, that's like, so morose.
>Yeah, well, you try not being morose when half your race "ascended", whatever of the stars that means, while leaving you behind. Politics' are navras'h, life-mate.
>Well - hey did the sky just get a lot darker?
>Heard you guys talking shit on the universal psychonet about Great Gaia like I wouldn't hear, you toothless aliums.
The bands around Jupiter are much more concentrated than what we get from the Sun. It's like taking all the radiation Jupiter receives from the Sun and focusing it into a belt around the planet. I don't know that you could put an object with Earth's mass in a stable orbit around Jupiter that's far enough out to avoid it.(Jupiter's Magnetosphere itself is larger than the physical size of the Sun)
That's all assuming that parking the Earth in Jupiter orbit somewhere doesn't fuck with the orbits of the Galilean Moons and send them crashing into each other or the Earth itself. Who knows what kind of havoc Jupiter's magnetic field would wreak on Earth's magnetic field too.
It is certain an interesting idea though.
>There's no star that spaceships have to get to to get to Earth
>They have to check Earth's location and current flight plan via the galactic network beforehand, then account for the time needed to get there via warp, and put their de-warp point ahead of Earth's current path based on how long the warp takes
>Also, they have to get a lifesuit if they want to set foot on Earth because too cold
>Its always easily to ask the humans to fly their planet close to your system to trade instead of sending your ships there
All the recent news about Jupiter's past deeds resulted in reading more about rouge planets. Haven't watched Diebuster but the Bronze Tribe in Heroic Age had hollowed-out planetoids to use as hiveships they could move to where they wanted it to be.
We could probably make a tourist industry on bringing alien species around to look at the remnants of our surface monuments by speeder and shuttle.
>"To your left, honored visitors from Vho'oord, is an ancient monument built in a time where construction was done entirely by human hands! No construction machines, no self-assembling smart structures, no psychic assemblers, no phase pylons, no building teleporter, no melodic N'anagdo growbone, no quantum format material printers! Just the blood, sweat, and lives of thousands of ancient humans."
>"And this monument, named after the people who built it, is known as the Great Wall of... of..."
>"... Benn, what were the people who built that wall thingy called again?"
>"I... hm... 'chinks', probably."
>"THE GREAT WALL OF CHINKS, VHO'OORDIANS!"
>"Ooooooooooooooooooooh, chinks, oooooooooooooooooh. Amazing chinks."
The Earth part of the tourism industry would be immensely expensive, and constantly changing prices, but totally worth the price if they are passing through a particularly beautiful(but dangerous) place.
>Earth flies in erratic flight paths, zipping past other planets, stars, etc and using them to gravity swing around to change directions and occasionally swinging into the orbit of a star to do trade
>Depending on which sector Earth is at, the ticket price can vary from being dirt cheap(In cases where its in orbit of a star for trade), to stupidly expensive(In cases where its flying to the hardest to reach and/or stupidly dangerous parts of the galaxy just to get a good gravity swing to change directions, like that time they plotted their flight path to pass near the galaxy's central blackhole)
>Not flying straight into them and forcing their spaceships into an atmospheric battle and attacking them when they are burning during atmospheric re-entry
>Not using the high speed impacts(on non-tourist areas, of course) of their spaceships to heat up the freezing planet if only for a little and also to salvage for the tech and scrap metal that we can trade
You are now aware that our Milky Way galaxy is in the process of eating the Sagittarius Dwarf Spheroidal Galaxy.
At least those stars aren't being gravstomped into the galactic center black hole or flung out into intergalactic space.
Well, most of them, I hope.
Life on nomadic planet Earth must be an insane mix of future and past social trends. I'm pretty sure somewhere out there is a sci-fi story dealing with the "origin remnants" of a spacefaring race a la mobile planetoid humanity to, say, humanity that opted to colonize a planet in a typical style of setting up a new home.
>Enemies once forced they way into interior of our planetary vessel to take our store of rare Jkatok screaming crystals.
>We drove them off using an ancient battle technique used by our enemies, called "shmup". It says that you must lure the enemy into an enclosed space stacked with stationary turrets and shoot everything that's free-flying inside.
>We got it from this ancient data unit here, stored in the Library of Heritage sector in our iron core habitat. We believe that it's 90 million cycles old. No, we cannot sell it to you, but you can buy these "credit chips" from us and operate it for a short amount of time to gain insight of its secrets.
>*vrrrrrrrr* "BLAST OFF AND STRIKE THE EVIL BYDO EMPIRE!"
>"INSERT TWO CREDITS."
It would be hilarious if the surface of nomadic Earth still has operational vehicles.
>Once, the Hytox successful dropped an large group of troops and land vehicles on Earth
>Its a well know fact that the humans don't have modern land vehicles due to their preference of space and aerial combat and their lack of use for such vehicles, however, the surface of Nomadic Earth holds many secrets that not all humans know about
>Unfortunately for the Hytox army, they dropped their forces on a place that used to be called 'Russia'
>The humans, following the lead of their elders, seek out the army of sleeping war machines spread out on the surface of 'Russia', the humans called them 'tanks'
>The Hytox could fight the air machines of the humans, but when the 'tanks' appeared, it brought not the plasma or energy weapons that every race had, it brought solid weaponry. A primitive weapon, yes, but to the Hytox who only had energy shields for defence, solid weaponry are their weakness, its able to hit their vehicles directly
>Taking pride in Hytoxian metallugy, they bet their lives on the armor of their vehicles.
>Unfortunately, the humans of the past took longer to figure out energy weaponry and thus were very hellbent on making their solid shell guns punch holes in everything from thick metal to concrete
I like that.
I wonder what they'll think if they found derelict sailboats that survived the conversion of our planet into a stellar vessel.
>"Guys this total proves my windsurfing theory."
>"What about this suit with flaps connecting the arms and legs and with this... er... primitive chemical rocket backpack? These look like they can fly too-"
>"Oh, that's for underwater exploration in those 'oshuns' that are now all dried up; you know, those connected bodies of water we still see on other planets. They move those flaps like the m'monga slugs you find in the coolant pools near the Third Sector Translight Drive."
>"... Steve, stop fucking with us."
>"Bob, we got a stranded tour group on the surface, their speeder broke down. Group #35, Speeder #26"
>"I told you to send that speeder to maintenance last week! Do we have spare speeders?"
>"If we had one I wouldn't be asking you for help."
>"Goddammit, I'll go up and find an operational vehicle on the surface to fetch them, send me their coordinates. They're the group with 20 people, right? I'll need to find a 'baz' or something if I want to fit so many people."
>"Bob, What on great Gaia is that?"
>"Its a 'baz' of some kind, from what it looks like, probably a 'skool baz'. But I have no idea why it grew wings and chemical rockets and flew to the destination."
>"The ancients have some weird stuff back then"
>"Yeah, I remember the time I found a 'turack' that turned out to be an alien and flew into space. What kind of crazy shit do they have back then?"
For the purposes of He-3 mining, it is. No one's going to be tapping the ice mantle or the core, and the atmosphere is ~97% H and He.
Galaxy collisions usually lead to them fusing over time - they pass through each other due to "inertia" but their high-gravity centers attract each other afterwards.
The sky would look more interesting after a good billion years.
It's not that it won't affect us at all (unless, as you say, something's actually aimed at our system, which isn't likely), but that the effects will be basically identical across the solar system so we won't care.
