North Node in Astrology

The North Node is not a body but a point: the place where the Moon's orbit crosses the ecliptic as the Moon passes north of it. The South Node sits directly opposite. In the astrological tradition, the North Node is read as growth and evolution, set against the South Node's innate wisdom from past experience.

North Node at a glance

• Also called: the ascending node; the dragon's head
• Symbol: ☊ (the South Node, or dragon's tail, is ☋)
• What it is: the point where the Moon's orbit crosses the ecliptic going north
• Partner point: the South Node, always directly opposite
• Motion: backward through the zodiac, one full circuit in about 18.6 years
• Time in one sign: about 1.5 years on average
• Traditional reading: growth and evolution; the South Node, innate wisdom from past experience

The Moon's path around Earth and Earth's path around the Sun lie in two different planes. Earth's plane, traced on the sky, is the ecliptic. The Moon's orbit cuts through it at two points, and those two points are the lunar nodes. The ascending, or north, node is where the Moon passes into the northern ecliptic hemisphere. The descending, or south, node is where it passes into the southern one. Because both points lie on the same line, they always stand opposite each other. Unlike the bodies on the list of planets in astrology, neither node is an object; each is simply a crossing point.

The nodes matter in astronomy because of eclipses. An eclipse needs the Sun, Earth and Moon to line up, and the nodes are what make that alignment possible, which is why eclipses arrive in eclipse seasons.

The nodes do not stay put. The plane of the Moon's orbit slowly turns in space, so the line joining the two nodes rotates too, by about 19.35° a year. Seen from above Earth's north side, the nodes travel clockwise. That is retrograde motion, against the direction in which Earth spins and circles the Sun. One complete trip around the ecliptic, called the draconic or nodal period, takes about 18.6 years.

The traditional names come from a mythological dragon. The ascending node is the dragon's head, written ☊, and the descending node is the dragon's tail, written ☋. Both symbols are used in astronomy and in astrology.

In astrology the two nodes are read as a pair, which follows from the astronomy: one cannot move without the other, and they always face each other across the chart. The tradition gives the South Node of the Moon innate wisdom drawn from past experience. It links the North Node with evolution and with what the tradition calls karma, or in plain terms, with growth.

Put side by side, the two halves can be read as a direction. The South Node then stands for what is already known and practiced, abilities that come without effort, and the North Node for what is less familiar and has to be built on purpose. In this reading the South Node side is not something to drop; what is already known becomes the base that growth starts from.

Past lives, life purpose and destiny, when they come up around the nodes, belong to the tradition's reading as well. They are not facts about a person, and nothing in a chart settles what someone's life is for. Astrology is an interpretive tradition, not a scientifically validated method, so whatever the nodes suggest in a chart is a theme to weigh, not an answer or an outcome.

Because the nodes take about 18.6 years to back through all twelve signs, they spend roughly 1.5 years in each one on average (18.6 divided by 12). While the North Node is in one sign, the South Node is in the sign opposite.

That pace shapes how the sign can be read. People born in the same stretch of about a year and a half have their nodes in the same pair of signs, so the sign describes a birth period more than a single person. Two people born a few weeks apart will very likely share it.

The house is the more personal layer. Houses need a known birth time, and the house of each node changes with it, so two charts with the same node signs can place the nodes in quite different houses. Because the nodes are opposite, they also fall in opposite houses.

Take an example chart with the North Node in Aquarius in the third house. The South Node is then in Leo in the ninth house. Read as a pair, the axis runs between those two signs and those two houses, and the tradition looks at both ends together rather than at the North Node alone.

FAQ

What is the lunar node? Either of the two points where the Moon's orbit intersects the ecliptic. The north, or ascending, node is the crossing heading north, and the south, or descending, node is the crossing heading south.

What is the South Node in astrology? It is the descending node, the dragon's tail (☋), always opposite the North Node. The tradition reads it as innate wisdom from past experience, the familiar end of the axis that the North Node's growth builds on.
