Currently known multi-planet systems around K-dwarf stars. Only planets with known masses are presented. The sample was retrieved from https://exoplanetarchive.ipac.caltech.edu/ on December 4, 2022. Giant planets with masses > 30 M_⊕ are shown in orange, and all planets with lower masses in blue. Terrestrial Solar System bodies are included for comparison (in red). The point size indicates the masses in M_⊕ of the observed planets. Note the different size scale of the different colored bodies (blue and orange). Additionally, the markers representing the Solar System bodies are enhanced by a factor of 10 with regard to the planets indicated in blue for better visualization.
