Its story

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.
