15 Cygni glides over the Northern Cross at 289 light-years, a yellow giant in a constellation shaped like a swan in mid-flight. Its G class makes it kin to the Sun, though older and far brighter. The Milky Way runs through Cygnus like a river of light, and 15 Cygni is one of many lit stones in its bed. A golden glow drifting above the galactic plane.
