Origin 100 BCE to 200 CE

The South Node of the Moon, called Ketu in Indian astrology, is the point opposite the North Node where the Moon's orbit crosses the ecliptic descending, the tail of the celestial dragon. It represents innate gifts, deeply familiar patterns, and the comfort zone brought into this life, the things that come so naturally they can feel like memory. In the karmic reading it describes talents and habits developed in the past, a place of ease and competence that can also become a rut, since retreating into it too often brings the flat sense of been there, done that rather than genuine growth. The healthiest use of the South Node is as a foundation and a springboard: a reservoir of skill to draw on while the person leans toward the unfamiliar lessons of the North Node. Its sign and house show where we are naturally fluent and where we are tempted to coast. Like a hometown one loves to visit but has outgrown as a permanent address, the South Node offers belonging and rest without being the destination.

The South Node of the Moon

The South Node, or descending node, is the point opposite the North Node, where the Moon crosses the ecliptic going south. Western tradition called it the Dragon's Tail, cauda draconis, and read it as decreasing, in the same way that the Head was read as increasing; the pair were treated as a modifying influence on whatever they contacted rather than as bodies with independent significations. In Indian astrology the South Node is Ketu, the severed body of the same demon, and it is read for detachment, loss, spiritual liberation and the results of past action, and is a full participant in the dasha systems by which Indian astrology times events. The modern western reading of the nodal axis as past and future lives, with the South Node as inherited habit and the North Node as the direction of growth, is a twentieth-century development, drawing on theosophical ideas of reincarnation, and is not found in the classical or medieval sources.

The node also carries the two periods that make it usable for timing. It regresses through the whole zodiac in about 18.6 years, so the nodal return falls at about nineteen, thirty seven and fifty six, and the nodal reversal, when the axis is exactly opposite its natal place, falls midway between. In the Indian scheme those figures are formalised: the Vimshottari dasha system allots Ketu 7 years and Rahu 18 out of a total cycle of 120, and both are handled exactly as the seven grahas are, with sub-periods and their own significations. The western tradition, having read the nodes as modifiers rather than as agents, developed no comparable timing use for them.

The South Node: The Same Axis, and the Same Two Definitions

The south node is the point where the Moon crosses the ecliptic going south, and it lies exactly 180 degrees from the north node by construction. Whatever is true of the one is true of the other reversed, which is worth saying plainly because the two are often listed as though they were independently computed.

Both share the mean and true distinction. The mean south node regresses uniformly, a full circuit in about 18.6 years, roughly 3 minutes of arc a day, always retrograde. The true south node is the instantaneous crossing of the Moon's real orbit and oscillates around the mean by more than a degree on a period of about a fortnight, going briefly direct several times a year. An ephemeris that gives one gives the other by adding half a circle; there is no chart in which they disagree about the axis.

The 18.6 year cycle is long enough to be visible in other things. It is the period of the principal nutation of the Earth's axis, and it governs the extremes of the Moon's declination, which swing between about 18.3 and 28.6 degrees over the same interval. That second effect, the major and minor lunar standstill, is the one archaeoastronomers look for in prehistoric alignments, and it is the same physical cycle the astrological nodal return is counting.

Eclipses occur near this node as they do near the north, and in the same seasons.

Names and Glyph

In the West the South Node is the Dragon's Tail, or Cauda Draconis, the counterpart to the Latin Caput Draconis and part of the same medieval translation of Arabic dragon imagery into European astrological vocabulary. In Indian astrology it is Ketu, the immortal tail severed from the demon Svarbhanu in the Vedic myth of the nectar of immortality, treated in Hindu astronomy as one of the nine navagrahas alongside the Sun, Moon and five visible planets rather than as a mere geometric point, a status the nodes never fully acquired in Western practice. Its glyph is the North Node's figure inverted, and the two symbols are consistently drawn as mirror images of one another across the medieval Byzantine manuscripts and later printed ephemerides that preserve them, a pairing that has held constant even as the artistic style of astrological glyphs has otherwise shifted considerably between antiquity and the present.

Where Hindu astronomy folded Ketu into a working system of nine grahas with its own dignities and periods, Western and medieval Islamicate sources generally kept both nodes as calculation points tied specifically to eclipse forecasting, a narrower role that the shared dragon symbolism nonetheless carried across all three traditions largely intact.
