Comparison to other small (i.e., M sin i ≤ 10 M_⊕) potentially habitable planets orbiting M-dwarf stars at less than 10 pc from the Sun. HN Lib b is highlighted in red, while the other planets are iterated between orange and blue for better distinguishability. The light green and dark green shaded areas denote the optimistic and conservative HZs of Kopparapu et al. (2013, 2014), respectively. The planet list was taken from the habitable planets catalog of the Planetary Habitability Laboratory at the University of Puerto Rico and merged with the composite planetary parameters table of the NASA Exoplanet Archive.
