The orbital period of Kepler 452b (shown in this artist's impression) is very similar to that of Earth

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.
Mission 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 "Earth 2.0" and the "closest so far" to our home.
