December 2038 lunar eclipse
A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, December 11, 2038,[1] with an umbral magnitude of −0.2876. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. Occurring about 3.3 days after apogee (on December 8, 2038, at 8:35 UTC), the Moon's apparent diameter will be smaller.[2] This eclipse will be the last of four penumbral lunar eclipses in 2038, with the others occurring on January 21, June 17, and July 16. VisibilityThe eclipse will be completely visible over northeast Africa, Europe, Asia, and Australia, seen rising over west and central Africa and setting over the central Pacific Ocean.[3] Eclipse detailsShown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]
Eclipse seasonThis eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
