This diagram represents all estrasolar systems within 65 light years (20 parsecs) that contain exactly two confirmed planets. The sizes of the icons indicate the relative masses (but not the relative diameters) of system components. Planetary masses are shown at a proportionately larger scale than stellar masses.

For more information on the systems summarized on this page, see the table below. For data on all known two-planet systems, see Characteristics of Two-Planet Systems. See also the comparative diagrams of Multiple-Planet Systems and Planets of Red Stars.
