A total lunar eclipse occurred at the Moon’s descending node of orbit on Thursday, November 7, 1957, with an umbral magnitude of 1.0305. 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 about 5.1 days after apogee (on November 2, 1957, at 11:30 UTC), the Moon's apparent diameter was smaller.
This lunar eclipse was the last of an almost tetrad, with the others being on May 24, 1956 (partial); November 18, 1956 (total); and May 13, 1957 (total).
