Rahu and Ketu: The Shadow Planets Explained

By Dr. R.P. Sharma — Vedic Astrologer, Ph.D. & M.A. Acharya, practising since 1979 · Updated 2 Oct 2026

Rahu and Ketu are the north and south lunar nodes — the intersection points of the Moon's orbit with the ecliptic. They have no physical body, which is why the texts call them chhaya grahas (shadow planets), but their effects in the chart are entirely real and, in my experience, among the most instructive planets to read. They always sit exactly opposite each other, dividing the chart along an axis that reveals the chart's central karmic tension.

Astronomical basis

Solar and lunar eclipses occur at or near the nodes — the Moon must be near Rahu or Ketu for an eclipse to happen. This is the origin of the mythological story: Rahu and Ketu are the severed head and tail of the asura Svarbhanu who swallowed the Sun and Moon before being cut by Vishnu's Sudarshana Chakra. The story encodes the astronomical truth: near the nodes, luminaries lose their light. Related: 12 August 2026 surya grahan (not visible in India — no sutak).

Rahu in the birth chart

Rahu functions like an amplifier. It inflates, obsesses, and intensifies whatever house and sign it occupies. People with strong natal Rahu placements often achieve remarkable worldly success precisely because Rahu removes the usual inhibitions around ambition, social convention, and risk. The sign Rahu transits or occupies shapes how that amplification expresses: Rahu in Gemini produces a very different quality of intensity from Rahu in Scorpio. Rahu does best when its depositor (the lord of the sign Rahu occupies) is strong and well-placed.

Ketu in the birth chart

Ketu does the opposite of Rahu: it releases, withdraws, and perfects. Where Rahu wants more, Ketu wants less. The house Ketu occupies often represents an area where the native has innate ability from past-life accumulation but little desire for new material from this life — a curious combination of competence and detachment. Ketu is also the karaka for liberation (moksha), and strong Ketu placements often produce people with genuine spiritual depth alongside unusual technical gifts.

Their 18-month transit

Rahu and Ketu complete a zodiac cycle in about 18.6 years, spending roughly 18 months in each sign and moving backwards through the zodiac. Their transit through your natal Moon sign or major natal planets produces noticeable shifts in life themes. The Rahu-Ketu axis transit activating the 1st-7th or 4th-10th house axis in a kundli frequently coincides with significant changes in relationships, career, or domestic life.

Where Rahu and Ketu are now

Period	Rahu	Ketu
May 2025 – 5 Dec 2026	Kumbha (Aquarius)	Simha (Leo)
5 Dec 2026 – June 2028	Makara (Capricorn)	Karka (Cancer)
From June 2028	Dhanu (Sagittarius)	Mithuna (Gemini)

Sidereal (Lahiri) signs, mean nodes; panchangs can differ by a day on the change dates. What the December 2026 shift means for each rashi: Rahu transit 2026 and Ketu transit 2026. To see which houses of your own chart they cross, use the Rahu Ketu calculator.

Rahu-Ketu dashas

In the Vimshottari dasha system, Rahu rules 18 years and Ketu 7 years. Rahu dasha tends to bring rapid movement, ambition, success through unconventional means, and sometimes confusion between real and desired identity. Ketu dasha often brings spiritual interest, losses that turn out to be liberating, technical mastery, and a stepping-back from worldly striving. Both dashas need to be read in context of the natal chart — their depositors' strength and the planets they conjoin or aspect matter as much as the node itself.

North Node and South Node — Rahu and Ketu

Western astrology's North Node is exactly what Vedic astrology calls Rahu, and the South Node is Ketu — the two points where the Moon's orbit crosses the ecliptic. The astronomy is identical; only the interpretive language differs. Western practice reads the North Node as the soul's growth direction and the South Node as the comfort zone left behind; Jyotish reads Rahu as the karmic amplifier of worldly desire, sudden gain and foreign paths, and Ketu as detachment, loss and moksha. If you searched "north node in Vedic astrology," it is Rahu you are reading about — and everything here on Rahu and Ketu applies directly.

Frequently asked questions

What are Rahu and Ketu in astrology?

Rahu and Ketu are the north and south lunar nodes — the two points where the Moon's path crosses the ecliptic. They have no physical body (chhaya grahas, shadow planets) but are read as planets in the birth chart, through the houses and signs they occupy and the dashas they rule.

Do Rahu and Ketu always move backwards?

The mean nodes, used by most panchangs, always move backwards through the zodiac, taking about 18.6 years for a full cycle and about 18 months in each sign. The true node wobbles and is briefly direct at times, but its overall motion is also backwards.

How long are the Rahu and Ketu dashas?

In the Vimshottari system Rahu dasha lasts 18 years and Ketu dasha 7 years. Venus (20 years) has the longest dasha and the Sun (6 years) the shortest.

Where is Rahu in December 2026?

Rahu moves from Kumbha into Makara on 5 December 2026 and stays there until about June 2028; Ketu moves from Simha into Karka on the same day.

What does Rahu with the Moon mean?

Rahu conjunct the natal Moon intensifies the mind — ambition, unusual thinking and at times restlessness. The Moon's sign, its strength and the rest of the chart decide how it shows. Persistent anxiety is a matter for a doctor, not a remedy.

Is the North Node the same as Rahu?

Yes. The North Node of Western astrology is Rahu and the South Node is Ketu; the astronomy is identical and only the interpretation differs.
