A lunar node is either of the two orbital nodes of the Moon; that is, the two points at which the orbit of the Moon intersects the ecliptic. The ascending (or north ) node is where the Moon moves into the northern ecliptic hemisphere , while the descending (or south ) node is where the Moon enters the southern ecliptic hemisphere.
A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Monday, March 25, 2024, [1] with an umbral magnitude of −0.1304. 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 ascending node of orbit on Saturday, October 28, 2023, [1] with an umbral magnitude of 0.1234. 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 Friday, May 5, 2023, [1] with an umbral magnitude of −0.0438. 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 ...
There will be 230 lunar eclipses in the 21st century (2001–2100): 87 penumbral, 58 partial and 85 total. [1] Eclipses are listed in sets by lunar years, repeating every 12 months for each node. Ascending node eclipses are given a red background highlight.
Sunrise occurs at the prime meridian when the Lunar phase reaches First Quarter, after one fourth of a lunar day. At this location the selenographic colongitude at sunrise is defined as 0°. Thus, by the time of the Full Moon the colongitude increases to 90°; at Last Quarter it is 180°, and at the New Moon the colongitude reaches 270°.
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.
