Lunar nodes

The Moon does not orbit in the same plane as the Earth and Sun; its path leans about five degrees off the ecliptic. Any two crossing circles meet at two points, and here those are the lunar nodes. Where the Moon climbs north through the ecliptic is the ascending, or north, node; where it drops south is the descending, or south, node. The two always sit exactly opposite each other. They do not hold still: the nodes slide slowly backward through the zodiac, completing a full circuit in about 18.6 years, spending roughly a year and a half in each sign. When a new or full moon lands near a node, you get an eclipse.

Tradition reads the nodal axis as a line of growth. The north node points to what you are meant to develop, the unfamiliar direction that stretches you; the south node marks the well-worn, the gifts and habits you already lean on and may need to loosen. Older texts call the north node the dragon's head and the south node the dragon's tail. Eclipses are said to activate this axis, which is part of why they feel so tied to fate.

Say a chart has the north node in Gemini and the south node in Sagittarius. A reader might describe someone who grows by staying curious, asking questions and listening to what is near at hand, while easing off the urge to have the whole answer already. Because the nodes move backward, that Gemini and Sagittarius placement lasts about a year and a half before the axis slips back into Taurus and Scorpio.

The nodes are points, not planets, so nothing physical sits there. The north and south node are always a matched pair, 180 degrees apart, never wandering off on their own. And there are two versions in common use, the mean node and the true node, computed slightly differently, so two charts can show the nodes a degree or so apart.

The NovaOracles birth chart tool plots your nodal axis, the moon and eclipses guide ties the nodes to eclipses, and why eclipses matter follows the axis through 2026.
