NASA scientists have discovered an Earth-like planet some 1,400 light-years away orbiting a star similar to the sun, they revealed during a press conference Thursday morning. The newfound planet, named Kepler-452b, is the smallest planet yet discovered orbiting the habitable zone of a G2-type star, like our sun. Of the1,030 planets discovered by NASA’s Kepler mission, this one is the most similar to Earth.
The mass and composition of Kepler-452b, which is about 60 percent larger in diameter than Earth is still unknown, but it is likely a rocky world. The planet is about 5 percent farther from its parent star than Earth is from the sun. The planet’s host star, named Kepler-452, appears to be 1.5 billion years older than our sun, at 6 billion years old. It has the same temperature as our sun and is about 20 percent brighter and 10 percent larger in diameter.
The Kepler-452 solar system is located 1,400 light-years away from ours in the constellation Cygnus.
