New planet found outside our solar system is just like Earth

NASA has found a new planet outside our solar system which is eerily similar to Earth in key aspects.

Scientists say the temperature on the surface of the planet is about a comfy 22C (72F). Its star could almost be a twin of our sun. It likely has water and land.

It was found in the middle of the habitable zone, making it the best potential target for life yet.

The discovery announced yesterday was made by Nasa’s Kepler planet-hunting telescope. This is the first time Kepler confirmed a planet outside our solar system in the not-too-hot, not-too-cold habitable zone.

Twice before astronomers have announced a planet found in that zone, but neither was as promising. One was later disputed; the other is on the hot edge of the zone.
