A partial lunar eclipse will occur at the Moon’s ascending node of orbit on Wednesday, July 18, 2046, with an umbral magnitude of 0.2478. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in the Earth's penumbra. 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. Occurring about 5.2 days before apogee (on July 23, 2046, at 6:35 UTC), the Moon's apparent diameter will be smaller.
