Question

Do you think humans could live on another planet besides Earth?

Answer 1

Of course they could. Though none in this solar system right now.  

Answer 2

Theoretically, as long as the atmosphere was identical. The air would have to be oxygenated, and there would have to be some sort of sustainable water and food source.  

Answer 3

yyes there is the pnet called supper earth

Answer 4

the same way that people can live in a house underwater.  Its not natural nor easy, but if you have the $$, air and water can be brought along, your domicile can be made strong enough to protect you... sure, its possible.

unlikely to EVER happen.

Answer 5

As long as the environment is the same and theres oxygen, I don't see why we couldn't.

Answer 6

Yeah!

Maybe the moon if we brought water.

Answer 7

Absolutely! And I wish some of them would. The conditions would have to be suitable to sustain the human body, of course, and it would help if the planet was previously uninhabited  as we wouldn't want to inflict our kind on others... at least not while we are incapable of treating Earth with any respect.

Answer 8

I think with our current technology that really isn't possible.  But you have to realize that humans have been evolving to adapt to earth's climate for millions of years.  Any planet we were to live on would have to have a nitrogen / oxygen based atmosphere with similar atmospheric pressure to earth, which means that the mass of the new planet would have to be very similar to earth's.  But if we can't even prevent global warming on our own planet, how could we ever expect to terraform a whole planet?  We are more worried about going to war over a natural resource that is about to run out soon and is going to pollute our atmosphere even more just to save a couple bucks at the pump.  As humanity, we are just ignorant and have our priorities in the wrong place.

Answer 9

If you mean another planet in our solar system, it would pretty much be a matter of "terraforming" it, or using technology to make it more Earth-like. None of the other 7 planets are habitable per se, so all of them would require some adaptation to support human life. Mars seems to be one of the easiest to terraform - scientists are talking about building hyperbaric geodesic domes that would be capable of holding in heat, maintaining an air pressure similar to that of the Earth, and contain an atmosphere similar to the one on our planet. Compared to the other non-Earth planets, these modifications are relatively simple, but even so, would prohibitively complicated and expensive. On Venus, a dome would have to be strong enough to resist the 100 atmosphere air pressure and keep out the 400-degree heat; on Mercury, too, there would need to be protection from overheating. Plus, a major difficulty of living on Mercury is that the solar day (i.e. the time between two consecutive sunrises or sunsets) is roughly 176 Earth days, which can disrupt a person's biological clock. As for the outer planets, constructing a capsule that could float atmosphere (there is no turf) that's prone to violent windstorms (like the Great Red Spot on Jupiter and the Great Dark Spot on Neptune), which would be the only way to make a habitable environment, would, likewise, be prohibitively complicated and costly.

As for planets outside the solar system, the answer really depends on which ones there are. Given the great diversity of the Universe, there are bound to be a few planets like the Earth that can support life on their own, or others that are easy to terraform. But before thinking about how humans can survive there, we have to find a way to get them there. As technology currently stands, travel to planets outside the solar system could take centuries or millenia.
