A planet called Kepler 22b is more like Earth than any yet discovered and has been identified as a potential future home for mankind.
Kepler 22b contains both land and water and has temperatures which average around 72 degrees (22 Celsius).
It also contains the right atmosphere to potentially support life.
It is, however, 600 light years from Earth.
The planet, where a year lasts 290 days, was first spotted two years ago.
However, Nasa scientists using the agency’s Kepler space telescope have now concluded that it offers the best hope yet for future human habitation outside the Solar System.
