Are there any other planets that humans could live on someday

Nearly 500 planets have been found outside our Solar System, ranging from the familiar to the weirdly unexpected. The discovery of dozens of super-Earths, planets with masses of roughly 5 to 15 times the mass of the Earth, implies that Earth-like planets are commonplace. NASA's Kepler Mission, now underway, will determine the frequency of habitable, Earth-like planets in our neighborhood of the galaxy. Once that frequency is known, we will know how best to design specialized space telescopes that will be capable of weighing and imaging these new worlds, and telling us whether their atmospheres show evidence of the molecules necessary for life (e.g., water and carbon dioxide), and possibly even those created by life (e.g., oxygen and methane). We will then know if any nearby stars harbor planets that are habitable, and perhaps even inhabited. We will know just how crowded the universe really is.

There are most likely millions of planets that are suitable for life in the Universe. Humans need oxygen, water, energy/food, and tolerable temperatures. The only problem would be being able to travel to these other solar systems, because the closest ones are still thousands (if not more) of light years away. (1 light year is approximately 6 trillion miles)

It depends how you define "live." Do you mean like humans do here on Earth, with no space suits/oxygen tanks/etc.? If that is the case, then there are none in this solar system other than Earth. There may be planets similar to Earth in other solar systems or galaxies, but it will take too long for any humans to ever get to them.

A human could live on Mars if he/she had the proper space suits, oxygen tanks, habitat, means of growing food, etc., but their lifestyle would be completely different from any here.

it could be possible, but I think any planet we inhabit is doomed just like this one. We don't respect nature or take care of this planet as it is.

Planet IDK :p

till now human knockledges are not aware of
any planet that have 50% of vital elements

probably there'll b my friend.

I think there r

yes but they are light years away from us, so getting there is a problem.
