Caption: Figure 1.
Eccentricity vs. semimajor axis of Earth-sized and super-Earth exoplanets orbiting M-type stars at distances of 10 pc or less. The size of the dot corresponds to the amount of insolation the planet receives (Earth’s insolation is shown for reference). Gray dots are exoplanets with unreported insolation due to multiple host stars. (From NASA Exoplanet Archive.)
