A super earth is heading for the earth at a speed of 500 thousand kilometers per hour. Can humans move there?

The earth is the origin of human life and the only place where human beings can live at present. However, with the rapid increase of human beings and the lack of various resources, our global environment is deteriorating. Faced with this situation, we humans have the idea of moving to other planets. Although it sounds strange, it's not a bad idea.

The Milky Way where our earth is located is 2.5 * 10 1 1? 1.5 *101star, and the Milky Way is just a tiny galaxy in the universe. In the observable 93 billion light-years universe, the number of galaxies similar to the Milky Way has exceeded 200 billion. Therefore, in the vast universe and ocean, there is likely to be a planet that can breed life like the earth. Super Earth is the focus of people's exploration.

Super Earth Super Earth generally refers to the earth-like super planet. When you hear its name, you should be able to think of rocky planets similar to the Earth, but their mass is larger than that of the Earth and smaller than that of ice giants such as Uranus or Neptune. The mass of the super earth is generally 1 to 10 times that of the earth.

Theoretically, there are habitable areas with different life ranges at a certain distance around the star, so it is very likely that one of the planets has the resources to breed life like the earth because of its moderate distance from the star and suitable temperature. Therefore, scientists preliminarily speculate that these planets are very similar to the earth in plate structure. They have a metal center mainly made of iron, surrounded by silicate mantle, and generally have canyons, craters, mountains and volcanoes on their surfaces.

Super earth is not? Earth? Super Earth has only some features of the Earth, such as rocky planets. Although it looks very similar to the color of the earth in appearance, it does not mean that the super earth is necessarily suitable for the existence of life.

At present, many super-earths have been discovered, but their positions can't judge whether they are suitable for life. Take Venus as an example. Venus is a terrestrial planet, but its surface temperature reaches 500℃, which is totally unsuitable for life.

Then there are the conditions of the super earth itself, whether it has the conditions of atmosphere, ozone layer, magnetic field, satellite and so on. And if all the conditions are met, life may not be born, what's more, the super earth still has some conditions that are not met.

Life on our earth is actually a special existence, which can be said to be the inevitable result of the development of the universe under countless accidental circumstances. Because the probability of life being born is too small and the requirements are very harsh, it does not mean that life will be born if there is a suitable environment.

Scientists have found that a super earth is crashing into the earth at a speed of 500 thousand kilometers per hour. In Ophiuchus, 6 light years away from the earth? There is a very small red dwarf near this star. It is called a red dwarf because its light is reddish and its brightness is only about 3% of that of the sun. In other words, even if it is so close to us, it is difficult to be found, and its mass is less than one seventh of that of the sun and its radius is only one fifth.

A red dwarf is a star. It was discovered in 19 16 by Barnard, a famous American astronomer. Later, in memory of Barnard, this star was named Barnard Star. Because this star is very close to the solar system, scientists have been observing it.

But some time ago, scientists finally found one around Barnard? Super earth? And named it Barnard B. Through continuous observation by scientists, the period of revolution of Barnard B is 233 days, which is three times that of the earth. Although it is in a livable zone, it is rich in atmospheric resources and has many characteristics similar to the earth, so scientists also speculate that it is likely to be rich in water resources.

However, because its brightness is too small, its radiation intensity is relatively small, its livable zone is very close to the star, and the orbital distance of the planet is too close, which leads to the tidal locking, that is to say, its back is not illuminated for a long time, so it is very cold. On the contrary, there is no night on its front.

As we said before, Barnard's mass is too small, so the intensity of solar radiation released by Barnard is also small, so the temperature on Barnard B star is as low as MINUS 170 degrees.

Of course, if there is water inside the planet, it must be completely covered with ice. In addition, the radius of the star is too small, and the energy released by the nuclear fusion reaction in the inner core is easy to directly impact outward, resulting in frequent and intense surface activities of the star and the release of star storms. Because Barnard B is too close to the star, it is extremely unstable because it is hot and cold.

Discovery of Barnard Star B Barnard Star B's parent star is Barnard Star, which was proved by the astronomical team of Carnegie Institute of Science with 20 years' data.

In fact, Barnard star B was discovered as early as the early 20th century, until astronomer Peter? Van der Kamp discovered the perturbation problem of Barnard's self-motion. Barnard swings every 230 days, which is probably influenced by the gravity exerted by its giant planet in its orbit. Therefore, the astronomer thought that Barnard's star should have a gas giant planet, but his statement was opposed by some astronomers until the team of Carnegie Institute of Science in the United States used seven instruments to observe the data for 20 years, thus verifying Peter? Van der Kamp conjecture.

Can humans emigrate? Don't take a look at the super earth out of context and think it is a super version of the earth. In fact, the super earth is only similar to the earth, but its environment is very different. Barnard star B is the title of a super earth, but in fact, the probability of life on it is almost zero, so the probability of human survival on Barnard star B is also zero.

First of all, when our scientists made a preliminary observation on this planet, they found that the brightness of Barnard star B is only 0.0035 times that of the sun, which shows that if there is less sunlight, it is not suitable for the survival and growth of creatures on earth, so this is a very unsuitable factor for human migration;

Secondly, although the surface of Barnard star B is covered with ice, that is to say, the water resources on the super earth exist in the form of ice, so its surface temperature must be very low, which may reach-150℃, which is not suitable for human migration from this point of view;

Finally, there may be super-Earths in every star, such as the nearest proxima centauri and the second nearest Barnard. At present, thousands of extrasolar planets have been discovered in the universe, including thousands of so-called terrestrial planets and hundreds of planets located in habitable zones, but these super-earths are not suitable for human habitation. The newly discovered Barnard star is a super-earth without living conditions.
