Scientists discover that two nearby planets have similar atmospheric and water resources to the Earth!

Two long-standing studies by two European universities recently found that beyond the solar system there is a large earth-like version of the planet known as k2-18b, which has much in common with the Earth, for example, itself It is also a rocky planet.In the course of the study, in addition to this kind of stars, around it there is another K2-18C of the stars, the research data from Chile's La Jola Observatory. Like the earth, the surface of this body of stars is likely to have water. It is one of the key messages that water resources are the survival of extraterrestrial life. In addition, although the planet is surrounded by rocks, it has the possibility of extraterrestrial life It is very small.

The two neighboring planets are in Leo, they are about 111 light-years away from the Earth, it is not easy to find extraterrestrial planets, the main researchers are very excited. The telescope's high-precision radial-speed planetary finder discovered the satellite, which calculated the speed (or how fast it was when it left or was close to the sun.) If there were other planets around the stars, then the speed would be Will be biased.How to determine if this planet is similar to the Earth or the reduced version of Neptune, scientists use the radial velocity of K2-18 stars using the formula to calculate the planet's own quality, with the existing radius and mass The density of the planet itself can be obtained, so that the planets are made of what kind of material. This calculation is more accurateIn the course of exploration, scientists found that the surface of this planet has a lot of liquid water. Its atmosphere is also similar to that of the Earth. A planet with abundant water resources may be more likely to have extraterrestrial life . In the relevant data analysis, scientists got some strange signals, these strange signals may come from other stars, so it was found around the k2-18b, the planet from the stars closer distance, the temperature Higher, it also has similar characteristics of the Earth.
