Eccentricity distribution of exoplanet orbits as a function of orbital period

Eccentricity distribution of exoplanet orbits as a function of orbital period. The eccentricities of the planets of the solar system and the orbits of xx are also given as a comparison. We see that the orbits of quite a few exoplanets are quite elongated. Source: https://www.ias.edu/ideas/2012/socrates-extrasolar-planets
