    'Earth 2.0' found in Nasa Kepler telescope haul

    http://www.bbc.co.uk/news/science-environment-33641648

    A haul of planets from Nasa's Kepler telescope includes a world sharing many characteristics with Earth. Kepler-452b orbits at a very similar distance from its star, though its radius is 60% larger. Nasa scientists said they believed it was the most Earth-like planet yet.

    Such worlds are of interest to astronomers because they might be small and cool enough to host liquid water on their surface - and might therefore be hospitable to life. Nasa's science chief John Grunsfeld called the new world the "closest so far" to Earth. ... Kepler-452b, however, orbits a parent star which belongs to the same class as the Sun: it is just 4% more massive and 10% brighter. Kepler-452b takes 385 days to complete a full circuit of this star, so its orbital period is 5% longer than Earth's.
