The solar system has a twin 130 light years away . It is about a series of planets, specifically nine, that orbit the star HD 10180 , according to the latest issue of the journal Astronomy and Astrophysics . Until now it was thought that the star only had seven planets.
The most interesting thing is that the two new planets identified are hot super-Earths that circle the star every 10 and 68 days respectively. Although they are too close to the star to maintain liquid water on its surface, they are solid rocky bodies similar to our planet, with masses between 2 and 5 times that of the Earth.
At the moment it is the most complete planetary system ever discovered, and a place to keep telescopes pointing, as suggested by Miko Tuomi and his colleagues at the University of Hertfordshire in the study's conclusions, based on data obtained with the HARPS spectrograph. .
