To-scale overview of the orbital configuration and naming scheme of the µ Her system. Components are colour-coded as Aa (green), Ab (red), B (yellow), and C (blue). The black curve traces the total sky motion of the system’s CM over a 40-year interval, combining a linear term (dashed grey line) with the annual parallax. Star symbols mark the positions on January 1 2026. Solid lines show the projected forward motion of each component over the next 40 years, and of the wide A–BC orbit over the next 400 years. To visualise the orbital inclination, segments closer to the observer are rendered in white and cast a shadow onto the sky plane; the transition between the white and grey segments marks the line of nodes. The inner A and BC subsystems are presented in greater detail in the right-hand panels.
