1. Tau Ceti f This planet is the first candidate to which alien life supposedly exists. Her location in the star system may be livable, if there is enough heat in her atmosphere and air.

2. Gliese 581d 2 Conducted studies allow suggest that the dense atmosphere of this planet contains a large amount of carbon dioxide. Planet about seven times more mass than Earth, it revolves around the “red dwarf” and is the “sister” of the planet Gliese 581g, also potentially suitable for the birth of life.

3. Gliese 163C This huge, rocky planet is seven times more in mass than Earth. She whirls around her dull stars in the constellation Golden Fish, at a distance of about 50 light years from us, and possibly inhabited by alien beings.

4. Tau Ceti e Planet Tau Ceti e is in the distance only 11.9 light-years from our sun. This world must be very similar to ours, except that the planet about 4 times more massive than the Earth. Also maybe her the atmosphere is too hot for the origin of life in our earthly understanding.

5. HD 85512b This planet is about three to four times more massive than the earth. She is in the constellation Parus, in the distance more than 35 light years from our sun. Scientists believe that soon confirm the fact of being on this planet necessary for water life.

6. HD 40307g HD 40307g rotates inside the habitable zone of your star. It is located 43 light years from our Sun in the constellation of the Painter. It is so close that using more advanced telescope will be able to look at her surface. She revolves around her parent star on distance of 90 million kilometers, while the Earth is 150 million kilometers from our sun.

7. Kepler-22b The planet Kepler-22b is 2.4 times larger than ours Of the earth. It revolves around a star, in size and temperature it is very similar to our sun. Scientists suggest that on this planet, whose surface temperature is 22 degrees Celsius, there is a greenhouse effect, and therefore life! Kepler-22bbe in the constellation Cygnus, at a distance of more than 600 light years from U.S.

8. Gliese 667Cc Gliese 667Cc is relatively not far from Earth, (about 20 light-years), located in the constellation Scorpio. This planet is 4.5 times larger than our Earth, it passes complete orbit around your sun in 28 days. Parent planet star is actually part of the triple star system and is a cold M-class dwarf star of mass approximately one third of the mass of our sun.

9. Gliese 581g The existence of this planet is still causes controversy. She was discovered in 2010, but her finding has not been scientifically confirmed. However, experts consider Gliese 581 a worthy candidate for a possible nucleation alien life. According to preliminary data, this rocky planet two to three times more massive than the Earth, it is located in the constellation Libra, more than 20 light-years from our sun.
