Sign in to saveAlso known as Kepler-20Ab, Kepler-20 b
Kepler-20b is an exoplanet orbiting Kepler-20 in a system 922 light years from Earth. It is classified as a Super-Earth, as it has a radius and mass greater than that of Earth. Its radius of about 1.87 would typically mean that it is a Mini-Neptune; but its high mass of 9.7 implies that it is an iron-rich rocky world. Along with the other four planets in the system, Kepler-20b was announced on 20 December 2011.
