Should We Be Excited About "Earth 2.0"?
NASA has called the exoplanet Kepler-452b "Earth 2.0." This distant cousin to Earth is larger than Earth, but orbits a star identical to the sun. It sits within a habitable zone, has a year about 20 days longer than an Earth year, and is only about 1.5 billion years older than Earth. Though this is the most Earth-like planet scientists have found so far, it's not exactly a close neighbor-Kepler-452b sits 1,400 light-years from Earth.
