descending node

The first at the descending node was on March 3, 2007.

The descending node is where it crosses to the south.

This eclipse occurred at the descending node of the moon's orbit.

The crossing from north to south is the autumnal equinox or descending node.

The points at which a planet crosses above and below its reference plane are called its ascending and descending nodes.

Saros cycle series 121 for lunar eclipses occurs at the moon's descending node.

Eclipses only occur in the eclipse season, when the Sun is close to either the ascending or descending node of the Moon.

This eclipse is the one of four lunar eclipses in a short-lived series at the descending node of the moon's orbit.

The required V for an inclination change at either the ascending or descending node of the orbit is calculated as follows:

The moon's path through the Earth's shadow near its descending node progresses southward through each sequential eclipse.

Lunar eclipses can occur only when the full moon occurs near the two nodes of the orbit, either the ascending or descending node.

Saros 129 for lunar eclipses occurs at the moon's descending node, repeats every 18 years 11 and 1/3 days.

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

Saros series are numbered according to the type of eclipse (solar or lunar) and whether they occur at the Moon's ascending or descending node.

During May transits Mercury has an angular diameter of 12" and take place at the descending node of Mercury's orbit.

The orbit is Sun-synchronous at 786 km altitude (14+3/10 revolutions per day) with a 10:30 a.m. descending node.

Transits occurring when Mars is at its ascending node are in May, those at descending node happen in November.

Similarly the descending node is the point where the Moon is descending from North to South, and is sometimes referred to as South node.

In Hindu astronomy, the ascending node is called Rahu and the descending node is called Ketu.

This element is then compared successively with all the left hand elements of the descending nodes and the process stops when all the conditions for an interval heap are satisfied.

Odd numbers are used for solar eclipses occurring near the ascending node, whereas even numbers are given to descending node solar eclipses.

Cat's Eye for Ketu (the descending node of the Moon),...these gems must be high-born (top quality) and flawless.

Series names beginning with "D" are near the descending node with respect to the Martian ecliptic, and occur when Venus has an angular diameter of approximately 18-19".

This eclipse series began in AD 1427 with a partial eclipse at the southern edge of the Earth's shadow when the Moon was close to its descending node.

It has the same orbit (798 km altitude sun-synchronous orbit with 6 p.m. ascending node and 6 a.m. descending node).
