May 2087 lunar eclipse
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 eclipses|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, 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 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. The first and last eclipse in this sequence is separated by one synodic month.| May 2 Descending node | May 17 Ascending node | June 1 Descending node |
