Link to main discussion of planetary systems around M dwarf stars

This diagram represents all confirmed planetary systems centered on M dwarf stars. 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. The horizontal scale indicating semimajor axes is discontinuous to accommodate crowded inner orbits.

For more precise physical and orbital characteristics, see this table. For more information on some of the systems summarized here, follow the links below. See also the comparative diagrams of Multiple-Planet Systems and Packed Orbits.
