The Sun serves as a unique and invaluable reference point, or "Rosetta Stone", for the study of other planetary systems. As the only star that can be observed with high spatial and temporal resolution, the Sun provides critical insight into stellar behaviour, exoplanetary formation, and star–planet interactions. We present our approach to interpret phenomena observed in distant exoplanetary systems in analogy to the Sun-Earth system, based on highly accurate characterization of the mother star through asteroseismology, coupled with the use of solar-driven space climate techniques to study the impact of the star's rotation and magnetic activity on the evolution of its exoplanets. Comparative analysis with solar-based approaches provide a powerful framework for interpreting the habitability potential of exoplanetary systems across the galaxy.
