Orbital architectures of known three-planet systems in the NASA Exoplanet Archive. Host stars are shown along the y-axis, with planet orbital periods on the x-axis. Marker size scales with planet mass, and marker shape distinguishes ﹩m\sin i﹩ measurements (triangles) from true masses (circles). The HD 190360 system is highlighted in green.
