Mean and median eccentricities

Mean and median eccentricities
Mean and median eccentricities Mean and median eccentricities in exoplanet systems and the Solar System as a function of multiplicity (number of planets in the system). As the number of planets increases, eccentricity decreases. The plateau in eccentricity at low multiplicity may be due to contamination of the one-planet data with higher-multiplicity systems. The “SS” denotes solar system planets.
