Kepler 452b, the second Earth, is as similar to the Earth as 80% (distance 1400 light years) (2)

Second, Kepler 452b is 1400 light years away.

And the distance from the earth is 1400 light years. According to the current fastest aircraft speed on the earth, it will take tens of millions of years to reach 452b, which has no practical significance for specific life exploration and immigration to this planet. We can't get there. What's the point of exploring? This is a great progress for all mankind, not to mention unlimited descendants. We can't see it now, but it doesn't mean we can't do it in the future.

Due to the lack of density data, human beings can't judge its material composition. But according to the discoverer? Is it reasonable? It is speculated that Kepler 452b is probably a rocky planet. Can't you say at present? Another earth? Still not? Another earth? And can only say yes? The closest to another earth so far? Exoplanet.

Many terrestrial planets discovered by human exploration, such as those discovered by humans? Little cousin? And then what? Big cousin? Earthlike planets can compare the past and future of the earth, especially through? Big cousin? Can let us see the future of the earth.

Experts say that the stars outside the solar system are too far away from human beings, and light can't travel for many years. So from a practical point of view, it is impossible to immigrate in the past. However, for astronomy, if human beings really discover that there is an Earth-like system in the universe, it is also very meaningful, which is very helpful for human beings to understand the universe and other star systems.
