[인사이트] In a space of 12.5 light-years, an Earth-like alien planet was found.

Researchers at the University of Göttingen in Germany discovered two extraterrestrial planets in the star Teegarden, 12.5 light-years from Earth.

These planets, called the garden b & # 39; and will probably have water and life around 1.1 times the Earth's mass.

12.5 light years away from human eyes, but the true garden is the fifth closest star to the Sun, following Proxima Kenta Wu, Alpha Keta, our binary A · B and Wagner.


The orbital period of & # 39; T & # 39; and & # 39; T & # 39; is 4.9 and 11.4 days, respectively. It can be seen that the distance from the tiger garden is very close to that of the Earth with an orbital period of 365 days.

Due to the proximity of the stars to the high temperature, life seems to be unavailable, but the temperature of the tea garden is only 2700 degrees, well below the sun.

Therefore, the garden b & # 39; and the garden is c- can maintain the proper temperature even if the distance is close to the star.

This is called the "Livable Zone". Researchers predict that the surface temperature of "Tea Garden b" will be between 0 and 50 degrees, and that liquid water will also be present.

The fact that the starry garden is about 3.5 billion years older than the sun, reaching 8 billion years, increases the likelihood of existence of garden b · c &. That's because life is too long to evolve.

"If we can confirm that there is atmospheric air, life is very likely," said Matthias Cachmeister, a professor at the University of Göttingen in Germany.

Meanwhile, the study was conducted at the Observatory of Cala Alto, Spain, with more than 200 observations of the stars with the equipment "Carmeness".

The research was published in the latest issue of Astronomy & Astrophysics.
