Evidence of the 'most similar planet to Earth ever found' spotted in old data

A planet with a similar surface temperature and size to the Earth has been discovered 300 light years away orbiting in its star's habitable zone. Kepler-1649c was discovered hidden away in data collected from the Kepler space telescope two years after it was retired by NASA and in seven-year-old observations. It's been described as'the most similar planet to Earth ever found' in data from the Kepler space telescope observations by the Search for Extra Terrestrial Intelligence. The rocky planet is just 1.06 times larger than the Earth and gets about 75 per cent of the starlight from its star that the Earth receives from the Sun. Astronomers from the University of Texas found Kepler-1649c while looking through old observations from 2013 - they found a computer algorithm had misidentified it.
