Lunar node
The lunar nodes are the orbital nodes of the Moon, that is, the points where the orbit of the Moon crosses the ecliptic (which is the apparent path of the Sun across the heavens against the background stars).
Rings Node Toolkits
This is a set of downloadable software tools developed at the PDS Rings Node. They enable users to perform a variety of common tasks related to planning ring observations, analyzing data, or carrying out dynamical calculations.
ascending node
The point in an orbit where a body traveling from south to north crosses a reference plane, such as the plane of the ecliptic (in the case of a Solar System object) or the celestial equator.
node -- the two points where a tilted orbit intersects a geometrical plane. The Moon's orbit intersects the ecliptic plane at the ascending node and the descending node.
Node One of two points at which an orbit passes through a reference plane (usually the ecliptic).
Oblateness The ratio of a planet's polar to its equatorial diameter.
NODE - Point where the orbit of a planet, as viewed from the sun, intersects the ecliptic. The ascending and descending nodes refer respectively to the points where the planet moves from S to N and N to S.
Node
(a) The point at which a standing wave pattern intersects the horizontal axis and at which the wave consequently has zero amplitude.

The point twice a month where the moon crosses the ecliptic. Once a month the moon crosses heading north and two week later crosses again heading south.

Ascending node: The plane of a planet's orbit (or other solar system object) is usually tilted with respect to the plane defined by the solar system (the ecliptic). These 2 great circles intersect at 2 points.

They start off by contacting a central control node, which tells the nodes about each other so they can communicate privately. Nodes move through many frequencies. They use a pseudo-random number generator to select the next frequency.
The discontinuity between successive full Moons and the Moon's return to its node prevents lunar eclipses from happening monthly. Successive full Moons (the synodic month) average 29.530589 days, whereas the Moon's return to the same node averages 27.

The Moon crosses from south to north of the ecliptic at its ascending node, and vice versa at its descending node.

Among these are three angles that define the spatial orientation of the orbit: i, the inclination of the orbital plane to the plane of the ecliptic; , the longitude of the ascending node measured eastward from the vernal equinox; and , ...
Pluto's ascending node, the point at which the orbit crosses the ecliptic, is currently separated from Neptune's by over 21°; their descending nodes are separated by a similar angular distance (see diagram).
This line will soon include an ascending node.
Incline the orbit an angle i, creating an ascending node due north of the orbit focus. This rotation 0° <= i <= 180° is performed along the negative x axis.
Draconic month: the interval between two successive passages of the Moon through the same node of its orbit.
Anomalistic month: the time between successive perigee passages of the Moon.
Traveling through the wormhole, they experienced difficulty in that, every time they passed through a verteron node, the protouniverse began to destabilize.
Longitude of the Ascending Node
The angle between the reference X-direction (typically the vernal equinox) and the point at which the body passes up (north) through the reference plane. This angle is often denoted as capital omega (Ω).
A eclipse year is the time between node passages. In 1994 it was 346.620073 days, and in 1995-1998, it was 346.620074 days, and in 1999-2000, it was 346.620075 days.

These occur only when the Moon is New and located on the ecliptic (it is on the node). Just by chance the Moon and the Sun have about the same angular size - they are both about 1/2 degree in size.
