Planetary distances (circular approximation) from the HZs in relation to the planetary eccentricities. The eccentricity is either the assumed value, an upper limit, or the actual eccentricity. The left panel conveys the full data set, whereas the right panel conveys a zoomed-in portion. Error bars for the non-zero eccentricities are given as well. HD 26161 is not included due to its outlying distance of 17.82 au. -- astro-ph.EP

There are more than 200 moons in our Solar System, but their relatively small radii make similarly sized extrasolar moons very hard to detect with current instruments.
