Can we live on other planets?

What humans are trying to find now is a planet with "alien creatures". These alien creatures may be primitive or low-level life forms, which can withstand extremely high or low temperatures and do not necessarily need oxygen. However, if we want to find a planet suitable for human habitation, we must have more suitable conditions, such as a suitable distance from the stars, water, oxygen and even the number and size of satellites. Recently, NASA announced the discovery of an Earth-like planet (codenamed Kepler -22b) with a diameter of Earth 2. four

Times, period of revolution is 290 days, which is a planet closer to the Earth. But when it comes to emigrating to another planet, we need to know more about the planet itself. However, I think that if human beings want to live on other planets, the first thing to be solved is how to cross such a long distance. Take Kepler -22b as an example, it is about 600 light years away, and it is still a long way to go there. In any case, exploring extraterrestrial planets is a good start. With the progress of science and technology, emigrating to another planet will not be just a dream.

I hope this solution can help you.
