No - Rahu and Ketu are not physical planets. They are the two precise points where the Moon's orbit crosses the Earth's orbital plane, known to modern astronomers as the lunar nodes. Vedic tradition still counts them among the nine grahas because the Sanskrit word graha never meant "planet" in the first place - it means "that which grips or influences".
That one detail changes how you read the entire Navagraha. In this guide we look at the real astronomy behind Rahu and Ketu, what ancient Indian scientists like Aryabhata actually wrote about eclipses, why two invisible points are worshipped as deities, and how UAE devotees should observe grahan on Gulf time.
What are Rahu and Ketu, exactly?
The Earth circles the Sun along a flat path called the ecliptic. The Moon circles the Earth on a path tilted about 5 degrees to that plane. Two tilted circles can only cross at two points - and those two crossing points are Rahu and Ketu.
Rahu is the ascending or north node, the point where the Moon crosses the Earth's orbital plane moving from south to north. Ketu is the descending or south node, where it crosses back from north to south.
The two are always exactly opposite each other, 180 degrees apart. They drift backwards through the zodiac, taking about 18.6 years for a full circuit - roughly 18 months in each rashi. Every panchang and astrology app you use today calculates them with the same mathematics modern observatories use for eclipse prediction.
If they are not planets, why are they grahas?
The confusion is a translation problem. In Western astronomy a planet must be a physical body. In Sanskrit, graha comes from the root grah, to seize or grip. The Navagraha was never a list of nine planets - it is a map of nine influences.
That is why the list can include a star (Surya), a satellite (Chandra), five visible planets and two mathematical points without any contradiction. Rahu and Ketu are called chhaya grahas - shadow influencers. They have no body, no mass and no light, yet they govern the single most dramatic event visible in the sky: the eclipse.
The eclipse connection - why the swallowing story is good science
An eclipse can only happen when the Sun, Earth and Moon line up at or very near one of the two nodes. A new moon near a node produces a solar eclipse. A full moon near a node produces a lunar eclipse. Away from the nodes, the alignment misses and nothing happens.
So when the Purans describe Rahu swallowing the Sun or the Moon, the location of the story is astronomically exact. Eclipses really do happen only at Rahu and Ketu. The ancients put the demon precisely where the shadow falls.
What ancient Indian astronomers actually knew
Long before telescopes, Indian astronomical treatises gave working mathematical methods to locate the nodes and predict eclipses. The Surya Siddhanta, Varahamihira's Panchasiddhantika and Aryabhata's Aryabhatiya all treat Rahu and Ketu as calculated points, not bodies.
Aryabhata, writing in 499 CE, stated plainly that eclipses are shadows - the Moon's shadow falling on the Earth, and the Earth's shadow falling on the Moon. Mythology and mathematics lived side by side in the same civilisation. The story carried the meaning, the math carried the prediction.
The story of Svarbhanu - one demon, two grahas
During the Samudra Manthan, the churning of the cosmic ocean, the asura Svarbhanu disguised himself and slipped into the line of devas as the amrit was being served. Surya and Chandra recognised him and alerted Lord Vishnu, who in his Mohini form severed the asura's head with the Sudarshan Chakra.
But the nectar had already passed his throat. The head lived on as Rahu and the body as Ketu - both immortal, both forever pursuing the Sun and the Moon who exposed him. Which is exactly what the nodes do. They are permanently locked to the paths of the Sun and Moon, and wherever they catch up, an eclipse follows.
What Rahu and Ketu mean in your life
As deities, the pair represents the two forces pulling at every human being.
Rahu, the head without a body, can taste but never be satisfied. He stands for worldly desire, ambition, obsession, foreign lands, technology and maya - the force pulling you into the world.
Ketu, the body without a head, has no appetite at all. He stands for detachment, intuition, past karma and moksha - the force urging you beyond the world.
In a kundli the two always sit opposite each other, splitting the chart into an axis of desire and release. When all seven other grahas fall on one side of this axis, the chart forms what astrologers call Kaal Sarp Dosh. We have covered that in detail in our complete guide to Mangal, Shani and Kaal Sarp Dosh remedies.
How devotees honour Rahu and Ketu
Because they have no physical form, Rahu and Ketu are usually honoured through the full Navagraha pooja rather than individual murtis at home. A few traditional practices, each done with intention rather than fear:
- Navagraha pooja - all nine grahas worshipped together, typically on Saturdays or during grahan periods. The Navgrah Dosh Nivaran Pooja Box carries the complete samagri for the ritual, and a Navratna set of nine sacred gemstones represents the nine grahas on a home altar.
- Japa - the beej mantras "Om Bhram Bhreem Bhroum Sah Rahave Namah" for Rahu and "Om Sram Sreem Sroum Sah Ketave Namah" for Ketu, chanted 108 times on a rudraksha mala. Tradition links the 8 mukhi bead with Rahu and the 9 mukhi with Ketu, while a 5 mukhi mala is the universal choice for daily japa.
- Saturday observances - as karmic teachers, Rahu and Ketu are often propitiated alongside Shani Dev. Devotees in node dasha periods or Sade Sati often keep a Shani Dev Pooja Box ready for Saturday rituals.
None of this is about fearing an invisible enemy. It is energy alignment with intention - acknowledging desire and detachment as real forces in your own life and choosing to work with them consciously.
Grahan in the UAE - dates and observance
The Indian community in the UAE often follows IST eclipse timings shared by family back home. Grahan observance, however, is based on local visibility. If an eclipse is not visible from your city, most panchangs hold that sutak rules do not apply there.
For the rest of 2026, no solar eclipse is visible from the UAE. The much-discussed total solar eclipse of August 12, 2026 passes over Iceland and Spain and will not be seen from Gulf skies. The next lunar event for Dubai, Abu Dhabi, Sharjah and Ajman is a penumbral (upachhaya) lunar eclipse on August 28, 2026 - and since the Moon only passes through the Earth's outer shadow, most panchangs do not prescribe sutak for it either.

Frequently Asked Questions
Are Rahu and Ketu real planets?
No. They are the two points where the Moon's orbit crosses the Earth's orbital plane, called the lunar nodes. They have no physical body, but their positions are calculated precisely and eclipses can only happen when the Sun and Moon align at these points.
Why are Rahu and Ketu included in the Navagraha if they are not planets?
The Sanskrit word graha means "that which grips or influences", not "planet". The Navagraha is a map of nine influences, which is why it includes a star, a satellite, five planets and two mathematical points without contradiction.
Why are Rahu and Ketu called shadow planets?
They are called chhaya grahas because they have no body or light of their own, yet they govern the shadow events of the sky - solar and lunar eclipses, which can only occur at these two points.
Did ancient Indians know what really causes eclipses?
Yes. Aryabhata wrote in 499 CE that eclipses are the Moon and Earth casting shadows on each other. Texts like the Surya Siddhanta gave mathematical methods to predict eclipses many centuries before modern astronomy.
How long do Rahu and Ketu stay in one zodiac sign?
About 18 months. The nodes move backwards through the zodiac and complete a full cycle of all twelve rashis in roughly 18.6 years.
What do Rahu and Ketu represent spiritually?
Rahu, the head, represents desire, ambition and worldly attachment. Ketu, the body, represents detachment, intuition and liberation. Together they form the axis of material desire and spiritual release in a kundli.
When is the next grahan visible from the UAE?
A penumbral lunar eclipse on August 28, 2026 - a subtle shading of the Moon visible from Dubai and the wider Emirates. No solar eclipse is visible from the UAE in 2026; the next one comes in February 2027.
Is sutak observed for a penumbral eclipse in the UAE?
Most panchangs do not prescribe sutak for penumbral (upachhaya) eclipses because the Moon passes only through the Earth's outer shadow. Sutak also applies only where an eclipse is actually visible, so always check local Dubai timings rather than IST.
Which rudraksha is associated with Rahu and Ketu?
Tradition links the 8 mukhi rudraksha with Rahu and the 9 mukhi with Ketu. For daily japa of their mantras, a standard 5 mukhi mala works for everyone - our rudraksha buying guide shows how to identify original beads.
