an exercise in miscellany

In general, super-Earths are defined exclusively by their mass, and the term does not imply temperatures, compositions, orbital properties, or environments similar to Earth’s. A variety of specific mass values are cited in definitions of super-Earths. While sources generally agree on an upper bound of 10 Earth masses (~69% the mass of the smallest Solar System gas giant Uranus), the lower bound varies from 1 or 1.9 to 5  with various other definitions appearing in the popular media.  Some authors further suggest that the term be limited to planets without a significant atmosphere.
