  2. Lunar node - Wikipedia

    en.wikipedia.org/wiki/Lunar_node

    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.

  3. Longitude of the ascending node - Wikipedia

    en.wikipedia.org/.../Longitude_of_the_ascending_node

    Denoted with the symbol Ω, it is the angle from a specified reference direction, called the origin of longitude, to the direction of the ascending node (☊), as measured in a specified reference plane. [1] The ascending node is the point where the orbit of the object passes through the plane of reference, as seen in the adjacent image.

  4. Orbital node - Wikipedia

    en.wikipedia.org/wiki/Orbital_node

    In the case of objects outside the Solar System, the ascending node is the node where the orbiting secondary passes away from the observer, and the descending node is the node where it moves towards the observer. [5], p. 137. The position of the node may be used as one of a set of parameters, called orbital elements, which

  5. Eclipse season - Wikipedia

    en.wikipedia.org/wiki/Eclipse_season

    An eclipse season is the only time when the Sun (from the perspective of the Earth) is close enough to one of the Moon's nodes to allow an eclipse to occur. During the season, whenever there is a full moon a lunar eclipse may occur and whenever there is a new moon a solar eclipse may occur.

  6. November 2040 lunar eclipse - Wikipedia

    en.wikipedia.org/wiki/November_2040_lunar_eclipse

    A total lunar eclipse will occur at the Moon’s ascending node of orbit on Sunday, November 18, 2040, [1] with an umbral magnitude of 1.3991. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow.

  7. Lunar theory - Wikipedia

    en.wikipedia.org/wiki/Lunar_theory

    The ascending node is the node passed by the Moon when it is tending northwards relative to the ecliptic. From these basic parameters, just four basic differential angular arguments are enough to express, in their different combinations, nearly all of the most significant perturbations of the lunar motions.

  8. November 2060 lunar eclipse - Wikipedia

    en.wikipedia.org/wiki/November_2060_lunar_eclipse

    A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Monday, November 8, 2060, [1] with an umbral magnitude of −0.9356. 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 ...

  9. January 2018 lunar eclipse - Wikipedia

    en.wikipedia.org/wiki/January_2018_lunar_eclipse

    A total lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, January 31, 2018, [1] with an umbral magnitude of 1.3155. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow.
