A total lunar eclipse will occur at the Moon’s ascending node of orbit on Thursday, February 11, 2055, with an umbral magnitude of 1.2258. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. 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. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring only about 15 hours before perigee (on February 12, 2055, at 13:00 UTC), the Moon's apparent diameter will be larger.
This lunar eclipse will be the third of an almost tetrad, with the others being on February 22, 2054 (total); August 18, 2054 (total); and August 7, 2055 (partial).
Visibility The eclipse will be completely visible over Africa, Europe, and west, central, and south Asia, seen rising over much of North and South America and setting over east Asia and western Australia.

Eclipse season
This 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.
