The group of astronomers of the Goettingen university in Germany and the British university [ad name=”Google Adsense-3 11″] in Herfordshira conducted new researches of a star of Gliese 667C and found round it seven candidates in exoplanets. Three of these exoplanets has potentially habitable zones. According to the scientists, six found exoplanets are very reliable, and a signal from the seventh, Gliese 667C-h, can be false. Nevertheless, uniqueness of system is not in a large number of planets, and the habitable zone, which is the area where existence of liquid water is possible. Three potentially manned planets in one system are now an absolute record. Besides, in Gliese 667C they occupy all possible orbits. For other planets in the habitable zone simply don’t remain places. All three exoplanets in a zone of a habitability appeared super lands. Their weight is more, than at Earth, but isn’t so great, as at gas giants Jupiter or the Neptune. It was succeeded to find new space bodies thanks to a combination of data from the most different observatories: “Very big telescope” (VLT), Magellan II, telescope of Kek and also a data archive of the HARPS receiver installed on the Chilean 3,6 meter telescope. Gliese 667C is part of threefold star Gliese 667 system and is located in 22 light years from Earth in constellation of the Scorpion. This most dim star in system and the habitable zone is located very close to a star — closer, than, for example, Mercury orbit.
