Probably about one hundred in the vicinity of the Solar System


Rocky planets not much larger than Earth are very common in the habitable zones around stars red weak. The international team believes that there must be tens of billions of such planets in our galaxy, the Milky Way, and probably about one hundred in the vicinity of the Solar System. This is the first time directly measured the frequency of super-Earths around red dwarfs, which account for 80% of the stars of the Milky Way. An international team just to make this the first direct estimate of the number of light planets around red dwarf stars. To do this, have used observations made with the HARPS spectrograph installed at the 3.6-meter telescope at ESO (La Silla Observatory in Chile).
