Can humans migrate to Kepler, and how do you determine that Kepler 452 is suitable for human migrati

With the development of mankind in the next 20 years, it is difficult for people to get there in their lifetime.

If you ask, you will help, but you won't.

Kepler has found 2,000 habitable planets! If the basic conditions are met, humans will migrate!

Kepler was a scientist, what are you trying to express?

Although scientists still need a lot of data to confirm that Kepler-452b is suitable for human migration, it is undeniable that Kepler-452b is indeed the most similar planet to the Earth's states discovered so far, and it receives just enough sunlight to meet plants, crops, and life systems like ours, and Kepler-452b is likely to have a rocky surface and a thick atmosphere, and may even have the conditions to support the existence of liquid water.

In general, to find a replacement planet for the Earth, three conditions usually need to be met, namely, the size of the planet, the orbit of the habitable zone, and the sun-like star. Kepler-452b has a radius twice the size of the Earth and a mass about five times that of the Earth, orbiting its "sun-like" star once every 385 days, and is in orbit in the habitable zone.

However, Kepler-452b's gravity level is twice that of Earth, and although this gravity property is still within the range that humans can overcome, the exact impact is unknown. In addition, according to the conversion of the distance between the star and the planet, scientists believe that Kepler-452b receives only 10% more energy from "sun-like" stars than the earth receives from the sun, which is basically equivalent to an increase of 10% in the earth's climate warming, which is also within the acceptable range of human beings, so many astronomers believe that Kepler-452b can be called the earth model.

Of course, the above calculation data are only the data deduced from the stellar evolution model, and there are many artificial subjective consciousness components in it. More importantly, Kepler-452b is located in the constellation Cygnus, which is 1400 light-years away from the Earth, and even with the current fastest probe, it will take 26 million years to go, so human attitudes towards Kepler-452b are limited to research, and the possibility of going to Kepler-452b in the future is basically zero.

1. Kepler-452 is a star with a g-type spectrum, similar to the Sun, with a mass about twice that of the Sun! 2. Kepler 452b orbital radius: astronomical units 3, orbital period:

385 days 4, planet diameter: times the earth These parameters are in addition to the size and the earth are a little different from the feast, it is simply a copy of the macro and simple earth revolution sun! In addition, an ideal habitable planet also needs to have a massive planet in the star system to guard, so that Yeyin can minimize the influence of many asteroids, comets and other uncontrollable factors outside the system, under the action of the huge gravity of the massive planet, these asteroids and comets are very likely to be attracted to its surface, or deviate under the action of gravity, so as to avoid the route to the habitable planet, so as to ensure the safety of the planet and the life on it.

Because Kepler 452 has a lot of earth squares similar to the earth, the magnetic field is similar, it has an atmosphere, and there are resources that humans can live in, and the earth's environment is very similar to the lead of the earth, which can allow humans to survive on the surface of the Shangwang wheel, so it is more suitable for human migration.

Because the air quality of this planet is almost the same as that of the earth, water resources are relatively abundant, and the pressure and gravitational force also meet the corresponding standards, the air is particularly suitable.

The earth's environmental temperature is very similar to the earth, and the soil resources are relatively abundant, so the planting of agricultural products can be improved, which can meet the basic needs of people's lives, and the temperature and air are more suitable for filial piety.

The planet is the right size, it has an orbit, it has water on it, it has air, it has a rocky surface, it has an atmosphere.

In July 2015, the Kepler Space Telescope discovered a g-type main-sequence star 1,400 light-years away in the direction of the constellation Cygnus, with a brightness of 20% and a mass of 4% more than the Sun, 6 billion years old. <>

The star's surface data alone is not very rare, but astronomers have unexpectedly discovered that the star has a planet located in the habitable zone, which is called Kepler 452b.

Although the planet was originally touted as a "super-Earth", Kepler 452b is only the sixth exoplanet most Earth-like in terms of the Earth similarity index, with Kepler 438b being the first, and there is another similarity that has not yet been officially confirmed.

Kepler 452 itself is just a star, not suitable for human habitation, the real possibility of habitability is its planet Kepler 452b, you must not confuse these two celestial bodies, but with the current level of technology, it takes 25.8 million years to reach Kepler-452b, so Keple-452b is just a symbol for a long time.

Neither the Hubble Telescope nor the Kepler Space Telescope can see the details of planets and stars, and can only determine their mass and possible atmosphere by passive methods such as spectroscopy, so Kepler 452b may not be suitable for human habitation, after all, its parent star Kepler 452 is twice the luminosity of the Sun, which means that Kepler 452b may have vegetation and smoke on it.

Our sun will also increase in brightness over time, and in hundreds of millions of years, the Earth's oceans will be evaporated by the sun, and the habitable zone of the solar system will also move towards the orbit of Mars or even Jupiter due to the increased brightness. <>

It is irresponsible to claim that a planet is habitable due to the limitations of today's observations, and observations spanning thousands of light-years are inherently inaccurate, and they only see the target thousands of years ago rather than in real time.

Compared to exoplanets thousands of light-years away, there are many new worlds in our solar system that can be modified, from the nearby Moon and Mars to the moons of Jupiter and Saturn a little farther away, most of these rocky planets in the solar system have water resources and atmospheres, which are ideal targets for future human colonization.

This is a star that is not suitable for human migration, there is no oxygen and no water, people have to die there, it is a terrible thing, Kepler 452 cannot live.

The decision that Kepler 452 is suitable for human migration is actually a new discovery for scientists on the road to finding, and the first one is determined to be a planet that can be migrated, but the surface is unknown.

Kepler 452 is indeed very similar to the living environment of our earth, but if human beings migrate to it, it will really take many years, or even as a last resort, people will not consider leaving the earth.

The first thing we need to know is that Kepler 452 itself is just a star, not suitable for human habitation, and the real human habitation has to be those rocky planets around the solar system.

Kepler 452, known as Earth's "cousin," has a ruling star similar to the Sun. Humans have been searching for life beyond Earth, and it is still unknown whether it is suitable for human migration.

When human technology is further developed, human beings have discovered that all celestial bodies in the universe are not eternal, just like the sun, although it now provides us with light and heat, the sun will change dramatically after 5 billion years. The hydrogen inside it reacts violently, and the sun burns for many years to cause it to be insufficient, so it expands externally to form a red giant. At this time, the celestial bodies around the sun will be swallowed by it, and even after expansion, the sun has directly reached the edge of the earth.

Therefore, when human beings can enter space, they have been looking for the next planet suitable for human life in the universe. But in the course of decades of exploration, humanity has achieved the most disappointment. Because they found that most of the planets in the universe were lifeless, either lacking temperature or liquid water.

But the hard work paid off, and after years of exploration, mankind finally found a more suitable planet for human habitation, Kepler 452b. <>

In fact, we don't have detailed information about the interior of this planet yet, but judging from its surrounding environment and some planetary characteristics, this planet is still good. His autobiography is similar to ours, and the official biography is more than 20 days longer than ours. It is 4 times larger than us, and 3 or 7 times more mass.

We all know that gravity increases with mass. So the gravity of this planet is twice as large as ours, but in reality this gravitational force is not very exaggerated. <>

At the same time, he is also relatively well distance from the stars in his star system. And the star is currently in a stable phase, albeit a little older than the Sun. It's such a good planet, why haven't scientists directly identified it as another habitable planet for mankind?

Mainly because he is so far away from us, a full 1,400 light years. If he hadn't blocked the light from the stars and was discovered by our telescopes, maybe this planet wouldn't be on our map of the universe today. And they want to determine the situation inside the planet, whether the temperature is suitable and whether there is liquid water.

With our current technology, there is no way to achieve it.

Kepler 452b is the only observable planet in this planetary system. It is relatively large, about 4 to 5 times the size of the Earth. The gravity above is about twice that of Earth.

It is tentatively concluded that it is similar to the structure of the earth, and is an out-and-out rock mass. And the star it orbits is about the same size as the Sun, perhaps larger. The brightness will also be a little brighter.

Our Sun is about 1,400 light-years away from the stars of the Kepler 452 system. In other words, it will take 1400 years to travel on a spaceship at the speed of light. This is enough time for human civilization to continue to evolve1 3.

The standard of the habitable planet we have been looking for so far is almost like looking for a twin brother of the Earth. The first is to have air, lots of water and the right pressure and gravitational pull. In this way, we have searched for a large circle of screening, which may be completely used as a substitute for the earth!

In other words, we are all looking for a so-called "habitable planet" according to the living conditions of carbon-based life. But it's no wonder that we've never set foot outside the solar system, or even inside the solar system. Other forms of life and the environment in which they live are completely unknown to us.

We cannot prove that humans are the only life forms in the universe, nor can we prove that carbon-based life forms are unique life forms in the universe.

The star of its galaxy is very similar to the Sun, and it is also a yellow dwarf star with a mass about twice that of the Sun; located within the habitable zone of the galaxy; Surface temperatures may be between -20-10 degrees Celsius; Revolution period 385 days; It is slightly larger than both the mass and volume of the Earth; From the above, we can judge that there is no problem with the temperature of this planet and it is very habitable; The mass is larger than that of the Earth, and its gravitational pull may form atmospheric conditions that are denser than those of the Earth; The density of the star is greater than that of the Earth, indicating that it is a rocky planet. More in-depth information, we can not get any deeper, because through the transit method of observation, we can only get some of the most basic information about exoplanets, but it is these conditions, scientists have given it a similarity index with the earth, which is a very high "achievement", which shows that Kepler 452b is a relatively good habitable planet, but as for other conditions to ensure the existence of life, such as whether there is liquid water, whether there is a magnetic field, etc., these are also necessary conditions. But there was nothing he could do.

Because the temperature on Kepler 452 is close to that of Earth, and there is liquid water, it is judged to be suitable for human migration.

Because Kepler-452 has a surface temperature comparable to that of Earth, and the planet has abundant water resources and atmosphere.

Scientists determine its mass by passive methods such as analyzing spectroscopy and the presence of an atmosphere, and that the planet is in the habitable zone of the star it orbits, and that the presence of liquid water may be habitable for humans.

Determine whether Kepler 452 has a water source or has traces of water sources, assess whether it is suitable for the atmosphere, and judge its undeveloped resource reserves.

Because Kepler 452 has the basic conditions for human habitation. If humans want to settle, they need oxygen and fresh water, which are basic conditions.

Because the same atmospheric structure exists on Kepler 452. In addition, there is water on this planet, so it is especially suitable for human migration.
