Kepler-452b, the “biggest” Earth brother. NASA has identified the planet “more similar” to our Earth thanks to the Kepler telescope.
That yes, a little far away, about 1400 light years in size and 60% above the Earth, is in the constellation Cygnus. Therefore, by size, it is considered a “super-Earth”.
Because the star it orbits, Kepler 186 is similar to our friend the sun star, the habitable zone of it is similar. Remember that our star is a type G.
All we know is that temperatures must be similar to those of our planet and therefore the possibility of liquid water are very high.
The orbit of Kepler-452b is 385 days, very similar to Earth. For the time and it is not currently known if has atmosphere or, if so, of what kind it is. If I then talked about how bored Kepler discovers planets and, as there is a way / theory of knowing if they have atmosphere and atmosphere, similar to that used with Pluto.
In case you have an atmosphere similar to ours, the chances that life may exist there are very high so that the following is to think a method to ensure that there really is “something” there. In this part we are still very green.
