Is Kepler 452b really suitable for human habitation?

NASA announced through the media that it had discovered an Earth-like planet 1,400 light-years away from us: Kepler 452b

This discovery was made through observation An Earth-like planet orbits a star with a mass similar to that of the sun, and Kepler 452b happens to be in the habitable zone of this planet.

According to data, the mass of this planet is 1.6 times that of the Earth, so it is called the "big cousin" of the Earth by netizens.

First of all, we need to know that Kepler 452 is a star similar to the sun. There is no unified standard for naming stars. There are various names depending on the time of discovery and different telescopes, but there are certain rules for naming planets. .

The names of extrasolar planets are generally a lowercase letter added to the name of the star, indicating that the star is the parent star of the planet.

These lowercase letters do not use "a". "a" is a special letter for stars, so the first planet discovered on the parent star is usually named after "b". Those discovered in the future will be named "c, d, e, f, g...".

Kepler 452b is the first planet discovered from the parent star Kepler 452, so it is named after "b".

Some scientists have inferred that there is liquid water and atmosphere on the planet. Water and atmosphere are crucial to the role of human beings. Therefore, this discovery gives hope to all those who are optimistic about "space immigration".

But, is Kepler 452B really capable of nurturing life like Earth? Is it suitable for people on earth to live?

If you want to know this question, you must first consider a habitable zone model. This is the minimum requirement that scientists put forward for a celestial body when summarizing the basic conditions for human life.

If humans want to be livable, they must first meet the basic conditions for human survival.

One: In the habitable zone of the galaxy.

Two: A star with sufficient lifespan and stability.

Three: It has a magnetic field that can resist "solar wind" and cosmic radiation.

Four: Have suitable atmospheric protection.

Five: Liquid water.

Six: Oxygen.

Seven: A large planet like Jupiter that can protect the earth from foreign meteorite attacks.

Scientists currently speculate that Kepler 452b is in the habitable zone, but the other conditions above have not yet been concluded. It is just assumed that if the above conditions are met, then this planet can meet the requirements for human habitability.

But all speculations and conjectures are only based on the data observed by the "Kepler" telescope. It is 1,400 light years away from us. Even if all the above conditions are met, our current level of technology cannot go there.

When we have the ability to go there, we cannot rule out whether there will already be intelligent life above.

So the earth is our only home at present, and we should cherish it.
