The Moon moves in an elliptical orbit with an average eccentricity of 0.0549. When a full moon coincides with its perigee (closest approach within 90% of perigee, roughly ≤ 360,000 km), it appears up to 14% larger and 30% brighter than at apogee (micromoon).
A lunar eclipse occurs only during full moon syzygy when the Sun, Earth, and Moon align near the lunar orbital nodes (the 5.14° inclination crossing points). Depending on node proximity, the Moon passes through Earth's penumbra or umbra.
Monthly full moon titles originate from Algonquin, Native American, Anglo-Saxon, and colonial traditions tracked by seasonal agricultural milestones—from January's Wolf Moon to autumn's Harvest and Hunter's Moons.
