Found the most similar planet to the Earth

Kepler-78b is the most similar planet to the Earth that astronomers have found so far.
It's located outside the Solar System, 430 light years away from our planet. It has similar mass and density to the Earth's, it's a rocky planet as well and it orbits a star similar to the Sun.
Even though the Earth and Kepler-78b both share the same physical characteristics, this recently discovered planet wouldn't be able to have any kind of life due to its extremely high temperature, which goes between 3000 and 5000ºC. Another difference is that Kepler-78b's orbit around its star lasts about 8 hours and a half, while the Earth takes 365 days to orbit the Sun.
This discovery has encouraged astronomers to keep looking for the Earth's twin planet, with the possibility of finding life along with it.
