Scientists just found an Earth-like planet that is a very promising candidate for hosting life. Of course, this discovery doesn’t mean that we actually found life on other planets. More precisely, the likelihood of life existing on other planets just became a little more realistic.
A planet that is at least 4.5 times bigger than Earth but is at the right distance from its sun so that it could be habitable has been discovered quite close to us.
Scientists believe that up to now this Earth-like planet 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 light-years 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 an accurate calculation of a planet’s size and mass, so it doesn’t allow us to determine its composition – at least for now.
But in any case, the discovery of an Earth-like planet of this kind sounds intriguing.
