Epsilon Sagitta
What is Epsilon Sagitta
Epsilon Sagittae lives in the small Arrow, one of the tiniest yet oldest constellations of the sky, already listed by Ptolemy in the second century. At 480 light-years, it is a yellow G-type giant in an evolved phase, with a surface expanded and cooled from its earlier life. Modest in brightness, its quiet light still helps trace the unmistakable silhouette of a celestial projectile suspended between Hercules and the Swan.
