The Earth phase, Terra phase, terrestrial phase, or phase of Earth, is the shape of the directly sunlit portion of Earth as viewed from the Moon (or elsewhere extraterrestrially). From the Moon, the Earth phases gradually and cyclically change over the period of a synodic month (about 29.53 days), as the orbital positions of the Moon around ...
A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Tuesday, July 7, 2009, [1] with an umbral magnitude of −0.9116. 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 ...

A partial lunar eclipse occurred at the Moon’s descending node of orbit on Thursday, December 31, 2009, [1] with an umbral magnitude of 0.0779. 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 ...
A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Monday, February 9, 2009, [1] with an umbral magnitude of −0.0863.

When the Moon's near side penetrates partially into the Earth's umbra, it is known as a partial lunar eclipse, [7] while a total lunar eclipse occurs when the entire Moon enters the Earth's umbra. During this event, one part of the Moon is in the Earth's umbra, while the other part is in the Earth's penumbra.

Due to tidal locking, the same hemisphere of the Moon always faces the Earth and thus the length of a lunar day (sunrise to sunrise on the Moon) equals the time that the Moon takes to complete one orbit around Earth, returning to the same lunar phase. While the Moon is orbiting Earth, Earth is progressing in its orbit around the Sun.
