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.
Ascending Node
The ascending node (Ω) is one of the orbital elements that must be specified in order to define the orientation of an elliptical orbit. The other orbital elements are inclination, and the argument of perihelion (ω).
ascending node -- the point in the orbit of the Moon where it passes from below the ecliptic plane to above (see node).
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.
Ascending node -- The point at which an orbit crosses a reference plane (such as a planet's equatorial plane or the ecliptic plane) going north.
Asteroids -- Small bodies composed of rock and metal in orbit about the sun.
Ascending Node The position in the orbit of a planet (or the Moon) where it crosses the plane of the ecliptic, moving northward.
Astigmatism An optical aberration resulting from unequal magnification across different diameters.
Ascending Node - The point in the Moon's orbit where it crosses the ecliptic from south to north

Ascending Node
In the orbit of a Solar-System body, the point where the body crosses the ecliptic from south to north: for a star, out of the plane of the sky toward the observer.

The ascending node of the Earth's mean orbit on the Earth's equator; i.e., the intersection of the ecliptic with the celestial equator at which the Sun's declination is changing from south to north. (see Catalog Equinox; Equinox.) [S92] ...
Since the ascending node is the point of intersection between the ecliptic and the plane of the lunar orbit where the Moon is ascending from the South to the North, it is sometimes called the North node.
Longitude of ascending node (1908.0), 74° 28.6'. Rotation period; latitude o° :24.46d 300:26.43d 60°:29.634 80°:30.56d Solar constant, or units of energy received per minute per square centimetre at earth's mean distance: 2 I calories.
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).
The opposite is ascending node or northbound node. desertification (NASA Thesaurus) The formation of a desert or the gradual expansion of a desertline into previously usable land, due to man-made or natural causes.
Passes start at the time the satellite crosses the equator from the southern hemisphere into the northern hemisphere (the ascending node). See orbit. 2. The period of time the satellite is within telemetry range of a data acquisition station.
If the Moon is traveling south to north, it's called an ascending node, and if the Moon is traveling north to south, it's called a descending node. Major and minor lunar standstills are determined by the location of the Moon's nodes on the ecliptic.
Odd numbers are used for solar eclipses occurring near the ascending node, whereas even numbers are given to descending node solar eclipses. For lunar eclipses, this numbering scheme is reversed.
At one node (called the ascending node) the orbiting star would be moving away from the Earth; this is the ascending node. At the other node the orbiting star would be approaching the Earth; this is the descending node.
orbit has an inclination of 5°9&minut; to the plane of the ecliptic, there are two nodes in the moon's orbit around the earth; the point where the moon in its orbit crosses from south of the ecliptic plane to north of it is called the ascending node, ...
[81] The longitude of the ascending node is the angle between the reference plane's 0 longitude and the planet's ascending 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 , ...
Orbital elements describing the orientation of an orbit are orbital inclination (i), ascending node (Ω), and argument of perihelion (ω).

a period of 19 days, 7 hours;
a mean distance from Sun of 0.1427 AU;
an inclination of 12° 10'; and,
an ascending node at 12° 59'.
Similar to terrestrial seasons, the Ls system is reckoned directly from the Sun's ascending node or Martian northern spring equinox position, where Ls = 0°. Each beginning season is 90° from the next one, e.g.
Nodes. The points at which the orbit of the Moon, a planet or a comet intersect with the plane of the ecliptic; south to north (Ascending Node), north to south (Descending Node).
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).
Secular resonances, in which two orbits interact through the motions of their ascending nodes, perihelia, or both, operate over timescales of millions of years to change the eccentricity and inclination of asteroids.
M]; perihelion distance (q), usually given in AU; eccentricity (e) of the orbit; and three angles (for which the mean equinox must be specified) --- the argument of perihelion (lower-case Greek letter omega), the longitude of the ascending node ...
