NASA recently discovered ten new Earth like planets outside of solar system.
Earth like planets are laying in Goldilocks Zone that is not too close or not too far to their star. That’s means the temperature of that planets are suitable for life.
The nearest such planet may be 12 light-years away and 1 light year is equal to travel of light in one year. On August 24, 2016, astronomers announced the discovery of a rocky planet in the habitable zone, the closest star to Earth.
