Overview
- The Moon reaches perigee the same day at roughly 221,817 miles (356,980 kilometers) from Earth, making this the year’s nearest full Moon.
- Best viewing is just after sunset when the Moon rises in the east, with clear outlooks recommended across North America and Australia.
- NASA notes supermoons can appear up to about 14% larger and 30% brighter than the faintest full Moons, though size differences are subtle to the eye.
- The horizon “moon illusion” can make it seem bigger at rise, a long-observed optical effect without a single definitive scientific explanation.
- This Beaver Moon is the second of three consecutive full supermoons in late 2025, with the final one due in December and only small tide increases expected.
