A great discovery that opens a whole new vein in telescopic exploration in the coming years opened the discovery of a new planetary system with two superterras that could have atmospheres with conditions for the formation of life.
This Thursday, the magazine Science publishes the finding of this system relatively close to Earth. 11 light years away and it has a red dwarf star that houses these newly discovered planets and is called GJ 887, it is half the mass of the Sun and an approximate temperature of about 3,400 degrees, about 2,100 degrees cooler than ours Sun.
Astronomy also has a very interesting possibility with this new planetary system, since next year 2021 the James Webb space telescope is inaugurated.
These characteristics, plus an atmosphere that will be analyzed to look for life traits, open a way to find life. The new worlds, which are called super-earths because they are rocky like Earth but larger, with four and seven times their mass respectively, take 9.3 and 21.8 days to complete an orbit.
It should be remembered that the closest planar plane system to our Solar System is Proxima Centauri, which has two planets and is 4.2 light years away.
The two superterras are named GJ887b and GJ887c, They have a minimum mass of four to seven times that of Earth and their discoverers believe that they are probably too hot to support life. Due to the distance they are from their star, they believe that they could not have liquid water because if it existed, it would evaporate.
However, there is hope, a third planet with a 50-day orbit and that would have a better chance of harboring life.
“If the presence of a third planet is confirmed in that star’s habitable zone, GJ 887 could become the most studied planetary system in our neighborhood,” Lund University professor Melvyn Davies said in a comment to the study.
