Which planet?

Question

If the Earth was to be destroyed in the next year, which planet would be the best to live on? And if it wasn't perfectly habitable, how would we colonise it?

And to those who say that 1 year is not long enough, I completely agree with you. So lets change it to at least 200 - 300 years. There we go, satisfied now?

And I need more answers, please!

Answer 1

mars, we would have to build big aquariums to keep the oxygen in. but odds are we would all just die if the world ended in the next year.

Answer 2

ya know if people are asking about this stuff why are a lot of people opposed to building bases on the moon? It sounds really out there but what if we seriously did need to find another place to live? And like some people have mentioned its too far for us at our current technology to go to mars or titan or wherever with billions of people so the moon would be a good close place. Of course their really isn't room on the moon for everyone but in a couple hundred years maybe we will be able to travel faster to mars and the moon will be a good layover stop.

Well that was supposed to only take one sentence and i guess i should actually answer the question lol so i would have to say in a few hundred years go to mars or one of the less deadly moons. As to colonizing the best bet would be terraforming and making an atomosphere because that seems like the best way to protect from cosmic rays and radiation.

Answer 3

Mars would probably be the easiest to terraform into an earthlike planet, though if the greenhouse effect could be eliminated, Venus is the planet closest in size to Earth.

No planet or moon is habitable now; space-station-like shelters would have to be built. There are theories on how a planet like Mars or Venus could have its ecology altered drastically enough to produce oxygen, water and all other conditions necessary for sustaining human life.

Answer 4

If Earth were to be distroyed next year, humankind would also be destroyed. At this time, we neither have the technology, manpower, or resources to inhabit and colonize another planet. There would be no "best" choice, because there is just no way it could happen, not yet anyway.

100 maybe 200 years from now, we will probably be much closer to the colonization of other planets/moons.

Answer 5

None of the other planets are even remotely habitable by humans without a lot of technical assistance. However, the one that comes the closest is Mars. Mars is suspected of having immense stores of water ice . . . some is locked up in the polar ice caps, the rest is locked up as permafrost. It, however, suffers from having an atmosphere roughly 1% thick as that of Earth and highly reactive and extremely fine dusty soil.

To render Mars into a habitable planet, one has to give it a thick enough atmosphere of the right composition. This atmosphere has to have a fairly substantial greenhouse effect (though you could reduce the need for this somewhat by constructing a large space-based mirror, or a series of them, to collect and focus sunlight onto Mars,) since you want to warm the planet enough for the subsurface ice to become liquid water. To do this, you may have to add additional greenhouse gasses or more water (depending on how much is currently locked up underground on Mars.) To do that, you need steer comets or icy asteroids at the far edge of the asteroid belt into Mars, and possibly set up factories on the surface to pump synthetic greenhouse gasses into the atmosphere.

Once that is done, you need to somehow create an oxygen atmosphere. Nothing too fancy, humans and many large mammals can get by on roughly a third less oxygen than is present on Earth now. You'd need industry, or swarms of genetically engineered algae and cyanobacteria to convert a fraction of the carbon dioxide into breathable oxygen, and other microbes to convert the ammonia brought in by cometary impacts into nitrogen. (Can't have too much carbon dioxide in the atmosphere, otherwise you'll suffocate the colonists.)

Optimistic estimates for the terraformation of Mars suggest the process could be basically complete in the space of centuries. Less optimistically, the process could take thousands of years.

In the meantime, what you'd want to colonize are the asteroids. One could dig tunnels into an asteroid, processing the minerals and metals in the asteroid to form the infrastructure of the new asteroid colony (and excess production can be traded with other asteroid colonies. Not all asteroids will have exactly the same composition.) Many have mineral hydrates, from which water could be extracted. Others may actually have deposits of water ice and other essential volatiles.

Answer 6

Well I guess Mars will be the only hope but we would need to send a whole lot of material and people there to make habitable living areas air locked against the thin, cold atmosphere of Mars. We would need to create huge hydroponic areas to grow food and we would need nuclear plants and lots of nuclear fuel to heat and energize the place.

Next, who would get to go and how many would go. I guess some of the rich would go. How would they choose who? I guess there would be many jumping off places from Earth with many rich pooling their money to make their own space craft..

All and all you and I and most everyone else would die and the survival of the Mars colony very precarious.

Answer 7

if the earth is going to be destroyed in one year, we may want to go to another planet but we must notice that the other planets are too far and it takes so much time to reach there,even there are not all the gases present there that we require.so earth is only the best planet.

Answer 8

to say that would be catastophic is an understatement. all the plantes stay in their respective orbit not just by centripical motion but by their own gavitational pull on each other. so everything would change. plus you didn't say what it was that caused the distuction did the earth just vanish? was it hit by a massive asteroid? what about the moon. there are many variables to consider. excellent question though

Answer 9

the planet orogeopheus. it is the fourth planet in a distant solar system with a star somewhat hotter than the sun, it is in another galaxy though. chances are we couldn't get to it before the space craft ran out of fuel.

Answer 10

i would like to die with my planet
but b4 that i would like to kiss the kiss the girl i love
after that i m ready to kiss death
n i would send my parents to mars coz life can be possible on mars
n dont destroy the earth soo soon 1 yr less to transport people coz only a handful can be transported in 1 yr

Answer 11

To answer your Question no Planet is Livable!! those planets have too much Nitrogen, Hydrogen, and other Elements you cannot name there is simply no planet But Earth that is best to Live on!!
