To which planet will humans emigrate?

Humans are going to immigrate to Mars.

Although it is impossible for mankind to leave the earth in a short time, in the long run, we should prepare the plan to leave the earth as soon as possible, because this plan will take not only centuries, but also generations of efforts. At present, if the planet closest to human migration in the universe.

Immigrants need conditions

When astronomers began to discover exoplanets outside the solar system, we realized how wonderful the world outside the solar system was, which provided us with a possibility that if the sun swallowed up our planet one day, human beings could go to their new homes ahead of time. Now we have discovered more than 4 100 exoplanets.

However, most exoplanets are not suitable for human habitation. Most of them are either ice giants like Neptune or gas planets like Jupiter and Saturn. Only 16 1 of these exoplanets can be called terrestrial planets.

That should be the B star of Centauri. Because its surface temperature is within the range that human beings can bear, and it may have an atmosphere suitable for human breathing, many scientists lock the planet that human beings can migrate to as Centauri B.

Centauri B orbits a red dwarf star called Centauri. This galaxy has three stars, of which Centauri is relatively small. It is only 7.5% to 50% of the mass of the sun, because the red dwarf Centauri is much smaller than our yellow dwarf sun.
