NASA astronomers discovered the smallest planet


Astronomers discovered the smallest planet outside our solar system. This is the first that is certainly rocky like Earth. Measurements of extraordinary precision-called Kepler showed that 10b is 1.4 times the diameter of Earth and a mass 4.6 times greater than he. However, because it orbits very close to its star, the exoplanet could not support life. The discovery has been hailed as "one of the deepest in the history of mankind."
