What is 4 Cassiopeiae

4 Cassiopeiae carries the deep stillness of a late M-type red giant, anchored in the queen's silhouette at 786 light-years. Its light departed when the European Renaissance was barely cresting the horizon of history. Cool at the surface and ancient in biography — one of those stars that seem to beat to the slow pulse of geological time.
