Discovering a `super Earth` with an average temperature of only 22℃, can the dream of human migration really come true?

Since humans were born with intelligence, we have constantly longed for the vast starry sky. Are there other civilizations among the countless stars in the sky? Are humans really alone?

At first, most scientists believed that there were no alien civilizations in the universe, but with the advancement of science and technology, the observable universe is becoming larger and larger.

After repeatedly refreshing their understanding, most scientists now agree that there could be extraterrestrial civilizations in the universe – there are more than 1 billion galaxies in the universe, in terms of probability.

After many years of observation by scientists, humanity has so far discovered more than 4,000 `super Earths`.

Humanity is constantly searching for a super Earth for many different reasons, but the most prominent is the desire that when the Earth is on the brink of destruction, we can still move to another place to continue to proliferate.

Anyway, the current Earth environment is getting worse and worse, and if humans cannot go deep into space and migrate to their second home before the Earth is destroyed, humans

Kepler-22b is one of many super-Earths discovered by humanity, first observed by NASA’s Kepler Space Telescope in 2009. The scientist who discovered it is named William Burrucci.

According to the data that William observed, Kepler-22b is located in the constellation Cygnus, about 638 light years from Earth, has a diameter 2.4 times that of Earth and a rotation period of 290 Earth days.

These factors are not enough to be considered `habitable`, other factors such as the distance between Kepler-22b and the host star, as well as the temperature and lifespan of the star,… are also considered.

Scientists named Kepler-22b’s host star `Kepler-22`.

However, because the mass and volume of Kepler-22 is smaller than the Sun, if the distance between Kepler-22b and the host star is approximately equal to the distance between the Sun and Earth, the temperature of Kepler-22b will be lower.

However, through many observations, research and calculations, astronomers have calculated the distance between Kepler-22b and the host star – only 85% of the distance between the Sun and Earth, which is possible.

Because of this, in December 2011, NASA officially announced that `Kepler-22b is the first planet in the habitable zone of a Sun-like star in the Kepler project`, but some scientists

If calculated according to the speed of humanity’s current rocket – 10km/s, it will take more than 18 million years for humans to reach Kepler-22b, and this time period is too long for humanity.

The fastest spacecraft currently developed by humanity is NASA’s Parker Solar Probe. When it gets closer to the Sun, `Parker`’s speed can reach about 692,000 km/h, equivalent to about 192 km.

And over this time, humanity may become extinct in space before reaching Kepler-22b.

In space, due to microgravity, human muscles change from a `stretched state` to a `relaxed state`.
