It appears in summer during 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.
