NASA’s Kepler mission, which was launched on March 7th, 2009, has confirmed the discovery of the first near-Earth-sized planet in the “habitable zone” around a sun-like star. This is considered to be another milestone in NASA’s journey to find another “Earth”.
Kepler-452b, as it’s named, is the smallest planet to be discovered in the habitable zone. The habitable zone, or Goldilocks zone, is the region around a star which planetary-mass objects with sufficient atmospheric pressure can support liquid water at their surfaces.
Kepler-452b is 60% larger in diametre than Earth, has an 385-day orbit and is 5% farther from its parent star Kepler-452 than Earth is from the Sun.
