Super Earth Exoplanets More Earth Like Than Thought. The planet GJ 1214b, shown here in an artist’s conception with two hypothetical moons, orbits a “red dwarf” star 40 light-years from Earth. GJ 1214b has a radius of about 2.7 times that of Earth and is about 6.5 times as massive, putting it squarely into the class of exoplanets known as Super-Earths. Image credit: CfA/David Aguilar.

Record Breaking Three Planets in Gliese 667C System Are Super Earths. This diagram shows the system of planets around the star Gliese 667C. A record-breaking three planets in this system are super-Earths lying in the zone around the star where liquid water could exist, making them possible candidates for the presence of life.

The numbers of planets discovered by Kepler sorted by their size distribution, as of May 2016, when the largest haul of new exoplanets was released. Super-Earth/mini-Neptune worlds are by far the most common. Image credit: NASA Ames / W. Stenzel.

The most common "sized" world in the galaxy is a super-Earth, between 2 and 10 Earth masses, like Kepler 452b, right. Where is ours? Image credit: NASA/Ames/JPL-Caltech/T. Pyle.
