A lunar eclipse is an astronomical event that occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. [1] Such an alignment occurs during ...
For the repetition of a lunar eclipse, the geometric alignment of the Moon, Earth and Sun, as well as some parameters of the lunar orbit should be repeated. The following parameters and criteria must be repeated for the repetition of a lunar eclipse: The Moon must be in full phase. The longitude of perigee or apogee of the Moon must be the same.
An eclipse of the Moon or Sun can occur when the nodes align with the Sun, roughly every 173.3 days. Lunar orbit inclination also determines eclipses; shadows cross when nodes coincide with full and new moon when the Sun, Earth, and Moon align in three dimensions. In effect, this means that the "tropical year" on the Moon is only 347 days long.
Like the lunar eclipse preceding it, this is the first of two partial solar eclipses slated for 2025, but the only one that will be visible in North America next year. ... This alignment of two of ...
And the eclipse ends as the moon returns to normal brightness at 4:47 a.m. This will be the only total lunar eclipse visible from the United States in 2025. (The next one will be on March 3, 2026).
The eclipse will peak at 10:44 p.m. ET, when roughly 8% of the moon’s surface will be in full shadow. This will come about 10 minutes after the moon becomes full at 10:35 p.m. ET.
The word is often used in reference to the Sun, Earth, and either the Moon or a planet, where the latter is in conjunction or opposition. Solar and lunar eclipses occur at times of syzygy, as do transits and occultations. The term is often applied when the Sun and Moon are in conjunction or in opposition . [4]
