What is Delta Sagitta

δ Sagittae is a red giant —of M type— that flickers with gentle variations over months. It marks the center of the tiny Arrow, a constellation as modest as it is ancient, already catalogued by Ptolemy in the 2nd century. Though small in apparent extent, its cool ruby dominates that small northern fragment of the summer sky.
