If humans had to one day leave earth due to, like, too much pollution or whatever, what other planets are habitable enough to move to?
-------------------------------------------------------
answers:
Manuel say: In our solar system there are none readily available, in other solar systems...who knows?

Ronald 7 say: Mars would be fit for the purpose with a bit of Terraforming
At the moment, its Gravity is about half that of Earth's and it has far too thin of an Atmosphere
It is because of its Mass of about 5/8ths of Earth
Without going into Alograthms and High Maths
Mars could be doing with a good beefing up
After all it seems that about 2.5 Billion years ago it got clattered by a big enough Protoplanet that left a crater about the size of Texas
It lost a lot of its Mass
At sometime, probably before the impact there had even been water running on its surface and quite obviously Volcanoes
It would have had a mantle and Magnetic core
But it was a fatal strike for Mars
Phobos and Diemos are literally doing nothing physically for Mars
Slowing their orbits down would make them drop to the Surface and crash
Asteroids could also be directed in, if not Comets
We have the Engineering
Eventually it could proquire 80% of Earth's Mass
That would stir up again its Gravity and Volcanoes
Revive it to what it once was
With a thicker and more mixed atmosphere
We could plant and turn CO2 Oxygen
It is not a matter if how it can be done
But when ??
-
quantumclaustrophobe say: So far - none that we know of.
-
Raymond say: None.
Certainly not in our Solar system. IF (a big if) there were still humans alive on Earth - despite the extreme pollution - that would mean Earth is still better (by a lot) than anything else in our Solar system.
It is possible to establish temporary camps on some other planets (and satellites) but that would mean bringing ALL essential elements. With the right equipment, the camp could manage to produce some basic things out of the local environment (oxygen, water) but we could certainly NOT arrive there and set up a colony (a camp with a chance of self-sustainability).

Eric say: There are no planets
-
Jeffrey K say: None. Right now, earth is all we have.
-
Acutrack say: It's impossible at this time because there is no such type of space ship to move with 7,714,576,923 numbers of passengers to space. Till we don't know the perfect planate where we can survive.
-
Jim Moor say: Sorry, it's not practical! Would take like 100,000 years to get there. If anything, we could maybe send some eggs, that's about it.
In short, at a maximum velocity of 56,000 km/h, Deep Space 1 would take over 81,000 years to traverse the 4.24 light years between Earth and Proxima Centauri.
We need to take care of our world, and I suggest we decrease our population before it's too late!

zeno say: None.

ANDRE L say: At this time, we don't know.

ChemFlunky say: If we had the resources and technology to terraform (that is, to make Earthlike) any of the planets in this solar system, we would probably also have the resources and technology to fix whatever we had done to Earth.
If we develop faster-than-light interstellar travel of some sort, we *might* find an Earth-like exoplanet around another star, but barring that, well, what we can see is about what we've got. We could probably establish bases, maybe even permanent, self-sustaining colonies, on the Moon (likely only because of its proximity, but it might end up being the jumping-off point for further exploration of the solar system), Mars (almost earth-like gravity, and at least some atmosphere to work with), and Titan (also a thick atmosphere, though much lower gravity), and possibly some of the other planets and/or moons, or in asteroids, or even just large space stations not affixed to any actual planet, but they are unlikely to be both large enough to hold any significant fraction of Earth's population and entirely self-sustaining (they might manage one of the two, but probably not both)
-
Josh say: None anywhere near, for sure. None that we can get to, certainly. It takes generations to build a self sustaining civilization on another planet. If we had to leave earth in a hurry, mankind would perish. Plain and simple.
-
STEPHEN say: None that anyone knows of.
-
Nyx say: There is no Planet 'B'.
-
jehen say: None that we know of. No matter what befalls the earth - be it a man made or natural disaster, if it is survivable by life as we know it, it will be far easier to make do with what is left of the earth than to take up residence on any planets we know of that we could actually get to.
-
Poseidon say: Although some Exoplanets have been discovered it is not know if any could support human life.
Even if a planet was found our present technological level would make it impossible to travel the vast distance to it.
Even if it was decided to launch a spacecraft to a planet we knew able to support life today with our current technology level the craft would have to be at least the size of a city because it would take probably 1000s of years to reach it and there would need to be facilities to carry food, produce food and water, and those who started the trip would have to procreate in order to sustain the life on board long enough for the ship to reach the planet.
There would also need to be services available such as schools, hospital bays, doctors, nurses, engineers, builder, the list is endless.
If we do destroy our planet with our greed or it is destroyed by external means such as a super volcanic eruption, asteroid strike or war that will be the end of us, or at least there would be so few survivors that their only priority would be to simply survive.

az_lender say: Serious scientists have studied the question of making Mars habitable. The proposition of McKay, Toon, & Kasting (Nature, 1991) calls for manufacturing CFCs on Mars at a rate that is probably not feasible. The proposition of Gerstell, Francisco, Yung et al. (PNAS, 2001) improves on this, providing a way to sustain a warm atmosphere with a plausible amount of fluorocarbon manufacture; but does not address the question of how to initiate a warm atmosphere on Mars. See later references to the work of Chris McKay with Margarita Marinova for further suggestions about terraforming. A 2017 article by Roberto Candanosa, published by the American Chemical Society, discusses the feasibility of growing green plants on Mars. All of these, put together, do not yet constitute a plan for living on Mars, but that is the question on which many disparate efforts are trying to converge.

say: Gov't is killing you with high frequency electricity.Theotokos Virgin Mary gave prayers to "Schema-nun Antonia" on how to save aborted babies from hell. If you pray these prayers diligently, aborted babies are released from hell. On each painted nail there are 40 demons. Smoking is censer to the devil.Using foul language calls upon Pagan deities (aka demons); Holy Spirit departs on 7 meters. People who use drugs see demons who cleverly disguise themselves as ghosts and aliens.America will be last country to switch to Euro (antichrist's world currency). Contraceptives = abortion;using contraceptives for 1 year = 5 aborted kids.Miscarriages happen because of high heels; cesarean because of tight pants (second generation cesarean will be infertile).Unbaptized aborted/miscarried/unborn babies burn in hell for until Final Judgement; if pregnant, keep the kid and deliver at home because kids are chipped using IVs and vaccines in hospitals. Dentists and doctors chip patients secretly. Ultrasound leads to mark of the beast; don't do ultrasound, please. Abortion leads to breast cancer; a demon is released from hell for each aborted kid. Dogs can become possessed; don't keep dogs inside your home [Pelageya of Ryazan]. Walmart has technology to administer mark of the beast to those who have cat bacteria in their stomachs; stay away from cats [Athanasius III of Constantinople]. Next false flag is the Statue of Liberty. Above earth there is ice (hemisphere); when rockets go up they bring ice down from upper sky to lower sky; ice stuck in lower sky will fall on us during Apocalypse. Earth is flat; earth stands on 3 pillars (the Most Holy Trinity); pillars stand on water at zero Kelvin; underneath this ice there is a bubble; and then the abyss. Zodiac is planetary prison of demons; don't believe in horoscopes or you'll exhibit the traits of the trapped demons. Most thoughts and dreams are from demons; demons never do good. Sleep fully clothed; pray the Jesus prayer. Pray to your guardian angel to have normal sleep. Vyacheslav Krasheninnikov was the last prophet before Apostle John (who wrote the Book of Revelation), Enoch, Elijah, resurrected Seraphim of Sarov, and resurrected Sergius of Radonezh will preach against the antichrist. Humans were created about 7525 years ago. Birds participate in time creation. It's a sin to kill birds. Dinosaurs live under our level; they will get out through sinkholes and lakes; to kill them, go for their nerves. Save the birds; but kill the dinosaurs. First dinosaur will come out of Volga River in Russia. Scientists don't see dinosaurs under our level because of radiation. Sinkholes happen because people dig for resources underground and because earth is heating up. Demons grow human skin (from a sample taken during abduction) and put it on so as to look like us. Demons will invite people to be healed inside their UFOs; those who go will be like zombies after. Gov't provides demons with diamonds and allows demons to abduct people. If you're being abducted, slowly pray the Jesus prayer. Don't panic. Demons use diamonds and souls to power their UFO craft. The bigger the diamond, the more it lasts. Demons have 4 UFO bases: 1)moon 2)inside fake mountain Kailash (Tibet) 3)in lake Baikal in Russia 4)in Atlantis which is underneath double ocean floor of Mariana Trench (Pacific Ocean). There are no aliens. Nobody lives on other planets. Airplanes that go down are hit by demons because they need the airspace to fight Jesus. Antichrist is pale with red eyes. He's possessed by Satan since he's 12 years old [Lavrentiy Chernigovskiy]. He flies super fast; deceived people will say: "Christ is here; Christ is there" when he's flying from one city to the next very fast. He wears gloves to hide long nails. He's surrounded by demons who appear as angels of light. Antichrist will trick people that he can do mountain moving and resurrection using holograms/hypnosis; fire from the sky is real because of pollution gases in the atmosphere. Antichrist will have food only for 6 months; then he will feed his 666ed people flour from mashed up turtles (Tavrion Batozskiy), but this won't be enough because 666ed people are 10 times as angry and 7 times as hungry as normal people even though 666ed people became shorter (3-4 feet tall = 80 - 120 cm) because nanochips do function of organs (organs diminish) [Nilus Myrrhgusher]. If you have a lot of nanochips in your forearm, then you will not be able to make proper Orthodox sign of the cross (last mercy for you will be to cut your forearm off). Nanochips are sprayed by the gov't using chemtrails; they're also in gov't food and medicine; so, eat food from your own garden. In case garden is destroyed by ice from the sky, have chickens for eggs and goats for milk (Paisios). Lipstick contains cells of aborted fetuses, dog fat, and placenta; human flesh is in McDonalds, Pepsi, toothpaste, antiaging, anticancer, vaccines, perfume, etc.; that's why you should not be using anything that modern society has to offer. You're better off hiding within a 10-12 people group in order to escape Apocalypse. During Apocalypse, Chrtistians will eat dirt from under pussywillowtree as it's filled with tears of Theotokos Virgin Mary; this water will flee if a 666ed person tries to get it. Barcode is Druid black magic curse; QRcode is Mayan curse; when food is scanned, it becomes dead because laser is a substance from demons. Don't go into a UFO to be healed by demons. Green 666 is given by isotope rays on wrist or forehead when people stretch hands to receive small plastic grey card with no name on it (World Passport). It doesn't just have to be during this procedure (could be anything you sign up for or anywhere where there is a secret scanner); biometrics (fingerprints, eyes scan) or getting picture for passport are very dangerous because they could mark you secretly. Gabriel Urgebadze said that they do it on index finger when they scan your finger. Basically, try to avoid new documents at all cost. Police will microchip and isotope ray people on highways. Chipped people will be influenced by computers to take grey plastic card; but when they do, green mark by isotope rays is given on forehead/wrist. Food stores will isotope ray people too. Antichrist will also release prisoners to mark people. Reject 666 at all cost because it leads to permanent hell. If you're about to be marked, pray the Jesus prayer. Hide with Orthodox Christians to escape 666; leave all electronics behind so that antichrist's minions can't track you; burn documents because they're from Satan. The Most Holy Trinity gives you a name during baptism; devil gives an antiname during antibaptism (ex. Social Security Number). People who die with these Satanic documents go to concentration camp in hell to await Final Judgement; once the BEAST Computer is burned down, souls will be released for Final Judgement. That's why you should give back documents of your deceased relatives back to the gov't so that the gov't cancels these digital antichristian names given during antibaptism by the beast system; or just burn these documents because gov't could get upset and could send demons to mark you because of this outright act of defiance. Prophecy from half a millennium ago describes Final Judgement like this: Jesus was very upset with people who had little boards (plastic cards) in their hands because they wanted discount from the antichrist. Give to charity in the name of Archangel Michael; he rescues people from temporary hell twice a year [at midnight September 18-19 and similarly on November 20-21; pray at these times on your knees remembering the deceased by names (adding "and relatives by flesh up to Adam") so that they are rescued if they're in hell] (or brings them up a level, that is, to a level with less punishment; eventually, people are freed). Feed the pigeons; when pigeons bow down, people are saved from temporary hell. It's a big sin to remember the dead with wreaths (because demons put these wreaths on their necks if they're in hell with their hands tied up behind their back while hanging by their hands), meat, alcohol, sweets, and worldly music. Demons print icons of saints in newspapers so that you throw these newspapers in the trash blaspheming these saints. Crosses on soles of shoes and back of pants are blasphemy. Demons make carpets with crosses and put them on sidewalks so that people walk on crosses. Playing cards mock how Jesus suffered on the cross: clubs (cross on which Jesus was crucified), diamonds (four nails Jesus was crucified with), hearts (sponge with vinegar that Jesus was given to drink),spades (spear with which Jesus was pierced).Cremation is devil worship; only blasphemers such as Lenin should be burned; if Lenin is buried, earth will be polluted, and China will attack Russia because of this.After China attacks Russia, Ruski Orthodox Tsar (shown by resurrected Seraphim of Sarov) will come to power in Russia;this Tsar will slay traitors inside church and gov't; as a result, Russia will be the only country not under the antichrist.Ecumenism = 263 heresies;each heresy leads to hell. In 2006 in Moscow (that's why Moscow will sink),representatives from most religions signed a document where it says that all religions worship the same Supreme Being [aka the devil]. Priests who participate in ecumenism will have Pagans walking on their heads in hell. Arkhimandrite Antonin Kapustin left a prophecy that Church of All Russian Saints in Gorny Monastery, Ein Karem, Israel will be blessed by forerunner of antichrist; Patriarch Kirill of Russia and Mark of Berlin blessed this church in 2007. When priests pray for current gov't (instead of praying for future Tsar),Jesus gets up from His throne and turns His back to them. Forgive me.
