It shines in the night sky every mid-summer fishing season, and its name is steeped in Native American folklore. The full moon in August acquired the moniker of Sturgeon Moon after the overabundance of the bottom-dwelling fish that for centuries helped sustain tribes around the Great Lakes region.
This year’s full Sturgeon Moon falls on Aug. 9 at precisely 3:55 a.m. Eastern Time. But it will also accompany a spectacular astronomical phenomenon worthy of setting your calendars by—a celestial alignment of six planets.
