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).
