In the research, experts discovered 24 super livable planets from 4,500 planets by exploring the age, volume, temperature and water source of stars, but none of these 24 planets fully met all the conditions, and the best one only met 4 of them. The research team also published a report in the American journal Astrobiology, detailing 24 super livable planets, some of which are older, hotter and wetter than the Earth. It must be emphasized here that although these planets are super livable planets, it does not mean that there is life on their surfaces. After all, human scientists have not found any life on other planets so far, which only shows that there are conditions suitable for life on the planet.

A super livable planet is currently defined as a K-class planet. If the planet is too old, it will lead to the gradual loss of geological vitality and even the loss of magnetic field in the end. But if it is too young, it will be unstable, and geological disasters will often break out or collide with other stars. At present, the surface temperature of K-class planets is about 3 degrees higher than that of the earth, and the oxygen content in the atmosphere is 25%-30%. The distribution of land and sea is similar to that of the earth, mostly shallow water areas. Finally, the K-class planet is larger than the Earth by 10%, so the resources are richer than the Earth. The planet that meets these conditions is the super livable planet, and it is the second planet that human beings consider living in.

The scientist in charge of the project said that the research project will help scientists to study other stars with James network telescope or Plato telescope in the future. Now the research team focuses on finding planets that are more favorable than the earth's conditions, and can't just stare at the earth. Although the earth is very good now, it does not mean that there are no better conditions.

Through observation and analysis, scientists know that in about 1 100 million years, solar fusion will be strengthened, the earth temperature will be too high, and the living conditions will be gradually lost. Because of this pressure, astronomers have been exploring new human homes. Some experts believe that there may be life on these 24 super livable planets. After all, they are all older than the earth, but in order to confirm, more rigorous research and exploration are needed in the future. But what is certain is that the earth is no longer the only living star of mankind.
