HD 219134 b is a Super-Earth exoplanet (a planet larger than Earth but smaller than Neptune), about 1.6 times the radius of Earth. Its scorching equilibrium temperature of 1015 K (742°C) makes it far too hot for liquid water. Despite its name, Super-Earths are not necessarily habitable; the term refers only to size. The planet completes one orbit around its star every 3.1 Earth days. It was discovered in 2015 using the radial velocity method. It orbits the K-type star HD 219134, located approximately 7 parsecs (21 light-years) from Earth.
