February 2055 lunar eclipse
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, 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 ; August 18, 2054 ; and August 7, 2055.
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 details

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| January 27 Descending node | February 11 Ascending node |
| Partial solar eclipse Solar Saros 122 | Total lunar eclipse Lunar Saros 134 |
