Astronomers have found four earth-like planets is 12 light years from our planet
An international team of astronomers found in the constellation Cetus (Tau Ceti) around the star remote from the Earth 12 light-years, four earth-like planets.
According to scientists, two of the planets are the supersense and are in the habitable zone, which makes them suitable for existence on the surface of the water. Due to the fact that the star is a red dwarf, and similar to the Sun, discovered the system is more favorable to life than the system TRAPPIST-1. A copy of the material scientists is published in the repository arXiv. The masses of the planets found reach of 1.7 Earth masses, making them among the smallest of the heavenly bodies, found near sun-like stars. To find these planets, it took delicate equipment, which is able to register small values of the radial velocity of the star (up to 30 centimeters per second).
With the introduction of new technologies to get rid of the noise in the data, the scientists were able to register the find. All four sites are rocky, but only the two most distant from the Tau Ceti planets potentially suitable for life. However, according to experts, they are likely exposed to a constant bombardment by comets and asteroids as a star surrounded by a disk of solid debris.
We will remind, in 2016, astronomers were able to detect the system TRAPPIST-1, which contains three exoplanets. They revolve around a red dwarf, distance from the Earth at a distance of 39 light years. While local star be a powerful emission of plasma.
