Astronomers have found a similar sized planet to Earth which could be habitable due to the temperature and atmosphere.
The planet called Wolf 1069 b, which orbits a red dwarf star, is a relatively close 31 light years away from Earth in the Cygnus constellation and it also has a similar mass to Earth.
While there have been more than 5,000 exoplanets - outside of our solar system - discovered since the first in the 1990s, there are only about a dozen which are in the labelled “habitable zone”.
