Humans can live on the planet Earth. Other planets are unsuitable for our existence unless new technology was able to assist humans in harsh environments.
Because we definitely need one to live on and work on.
None are known.
Us humans are rather finicky about the conditions we can live in. It can't be too hot, it can't be too cold, there has to be water to drink and air to breathe. The gravity has to be about what it is on Earth and so on... As far as we know at the moment no, as there are currently no planets that we know of with the necessary temperature, gravity strength and atmospheric composition for humans to survive. We can only know this about the planets in our solar system however.
Currently, Earth is the only known planet where humans can live without significant technological assistance. Mars is being explored as a potential future habitat for humans, but it would require significant infrastructure to make it habitable. Other planets in our solar system are either too hot, too cold, or lack the necessary resources for human habitation.
No. Humans have never been farther from Earth than the moon. Currently, barring a handful of astronauts on the International Space Station, all humans are on Earth. People could never live on Neptune. It has no solid surface and is far too cold.
The basic requirements of human beings are air and water, if these two things are present on any planet, then it can be possible to live on that, but unfortunately our astronomers did not able to find any of such planet, but in future it can be possible. So hope for the best!
Very probably
Not for humans.
Probably not on Mercury or Venus, but speculation suggests we might have colonies on Mars some day.
No one can answer this question as we do not have any proof of whether they do or don't. Some believe that there are planets out there that are the right distance from the sun have the same size sun and planet as ours and have similar atmospheric conditions. If there are such planets, it is possible that a human or human-like species could live and thrive there.
it could be because humans are interested in finding planets that had water sources and places suitable for humans to live in.
Of course, with properly pressurized suits and sealed, pressurized environmemts. There are no known planets where humans could live in the open as they do on earth.
Because we definitely need one to live on and work on.
None are known.
It wouldn't support humans, but some extremophile bacteria could probably live there just fine.
The history of the planets had nothing to do with humans. Humans used the planets as religious symbols.
Because If Aliens are real then they are said to have come on different planets which we can't live on so they are different
