Scientists believe that up to now it is the most probable planet to host life. Even though they haven’t managed to find out if it is solid like Earth or is a gaseous giant.
The planet candidate for life is only 22 lightyears from Earth and lies in the constellation of Scorpio. It’s called GJ-667Cc and orbits a star, which in its turn orbits a pair of stars. It means that it has three suns, but two of them are far away – they just shine more than other stars in the night sky.
The GJ-667Cc is located very close to its parent star GJ-667C, much closer than the Earth to the Sun. That’s why its year lasts only 28.15 days. However, as far as the GJ-667C is a dwarf star the level of its radiation is perfect for life.
“The GJ-667Cc is located right in the middle of a particular habitable zone, right in the point where the Earth would be if it was located in this solar system” explained the scientists from the University of Göttingen in Germany, who made this discovery.
However, researchers haven’t managed to determine if the GJ-667Cc is solid like Earth or gaseous like Neptune. It has to do with a recent method, used by scientists, which doesn’t provide accurate calculation of size and mass of a planet, so it neither allows to determine its composition – at least for now.
