Nasa has found a twin Earth orbiting a star like the sun in the Milky Way which scientists say "would feel a lot like home".

Astronomers have found a planet they say is "the closest twin to Earth" ever seen. Named Kepler-452b, it is the smallest planet discovered orbiting in the habitable zone of a star, and has been described as an "older, bigger cousin". What makes this planet remarkable is that it orbits its star at about the same distance that Earth orbits the sun. What's more, its home star looks to be similar to our sun.
