Earth’s companion has allowed astronomers to define lunar cycles, navigate without technology, and understand celestial ...

The point where the moon's orbit crosses the Earth's orbital plane going from south to north is called the ascending node and when it is crossing from north to south it's called the descending node.

There are two types of nodes, an ascending and descending node. If the moon intersects the ecliptic going from south to north, it's considered ascending, with the opposite for descending.

Three factors affect the slope of a solar eclipse’s path of totality: the distance of the Moon from the node, Earth’s season, and whether the eclipse occurs at the ascending or descending node.

before banking south to the shuttle landing field. This landing pattern is called a descending node -- normally space shuttles returning from the space station approach from the southwest -- which ...

On Monday, that particular point will be in the constellation Leo, while the descending node is in Capricornus. Now, go back and look at the table again. Note that the eclipse seasons occur a few ...

We call that crossing point a "node." Also, during that eclipse, the moon crossed the ecliptic going from north to south — the descending node of its orbit. Two weeks later, on March 29 ...

The moments when Pluto transitions across the ecliptic are called nodes. In this case, Pluto is passing from above the ecliptic to below it, which makes this specific point Pluto’s descending node.
