A total lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, May 17, 2087, with an umbral magnitude of 1.4568. It will be a central lunar eclipse, in which part of the Moon will pass through the center of the Earth's shadow. 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 2 days after apogee (on May 15, 2087, at 15:25 UTC), the Moon's apparent diameter will be smaller.
Visibility The eclipse will be completely visible over east and southeast Asia, Australia, and Antarctica, seen rising over much of Africa, central and eastern Europe, and west, central, and south Asia and setting over the central and eastern Pacific Ocean.

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. The first and last eclipse in this sequence is separated by one synodic month.

Lunar eclipses of 2085–2088 This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.
The penumbral lunar eclipses on January 10, 2085 and July 7, 2085 occur in the previous lunar year eclipse set.
