The North Node and South Node, together called the lunar nodes, are the two points where the Moon’s orbit crosses the ecliptic, the Sun’s apparent path through the sky. In astrology, the South Node stands for what you already know how to do, and the North Node for the direction you’re meant to grow in. Together they work like a compass laid across your birth chart.
In a chart you’ll see them as two symbols among the planets: ☊ (North Node) and ☋ (South Node). They aren’t planets or bodies of any kind. They’re calculated points. The North Node is where the Moon crosses the ecliptic heading north, and the South Node is where it crosses heading south. Solar and lunar eclipses can only happen when a new or full moon falls close to one of them.
The two nodes are always exactly 180° apart, so they form a single axis through the chart. Modern astrologers give that axis one of the deepest meanings in the whole chart: where you’re coming from and where you’re headed.
The idea is old. Greek-speaking astrologers of antiquity already tracked the nodes because of eclipses, and medieval astrologers called them the Dragon’s Head and the Dragon’s Tail. In Indian (Vedic) astrology they’re Rahu (North Node) and Ketu (South Node), and they carry as much weight as the planets. The reading most Western astrologers use today, the nodes as a guide to purpose and growth, took shape in the 20th century, influenced by theosophy and by writers such as Dane Rudhyar and Martin Schulman.
