A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Friday, July 16, 2038, with an umbral magnitude of −0.4938. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into 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 4.9 days before perigee, the Moon's apparent diameter will be larger.
