Supermoon dates and sizes

2 full Moons in 2026 meet361400 km or closer.

“Supermoon” has competing distance thresholds. This selection applies one stated rule. The default uses 361,400 km; the annual-range option uses the farthest full-Moon distance minus 90% of the full-Moon distance span in the selected year. A closer Moon subtends a larger angle; the disc’s angular area increases with the square of its diameter. Micromoons use405,000 km or farther.

Compare full Moon distances and apparent sizes under three explicitly named Supermoon thresholds, with micromoon contrast.
