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).

Visibility

The eclipse was completely visible over the eastern half of Asia, Australia, and Alaska, seen rising over the western half of Asia, Europe, and much of central and east Africa and setting over much of North America.

Saros 135

This eclipse is a part of Saros series 135, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on April 13, 1615. It contains partial eclipses from July 20, 1777 through October 28, 1939; total eclipses from November 7, 1957 through July 6, 2354; and a second set of partial eclipses from July 16, 2372 through September 19, 2480. The series ends at member 71 as a penumbral eclipse on May 18, 2877.

The longest duration of totality will be produced by member 37 at 106 minutes, 13 seconds on May 12, 2264. All eclipses in this series occur at the Moon’s descending node of orbit.
