Astronomers found out that the “second Earth” was part of a triple system.
Astronomers have announced that Proxima Centauri is the star, near which was discovered a “second Earth” is part of a triple system and revolves around the double star alpha Centauri.
First time scientists were able to determine accurately the orbit of Proxima Centauri and to establish that it revolves around the alpha Centauri AB with a period of 550 thousand years. The minimum distance from Proxima Centauri to the binary system is 4.3 thousand astronomical units and a maximum of 13 thousand.
The speed of movement of Proxima Centauri in space, according to scientists, is different from that of alpha Centauri AB by only 270 meters per second — half of this quantity enough to first Shine was not absorbed by the second.
Distance from Proxima Centauri to the Sun is 4.24 light years away.
