Ketu is the body left behind after the head became Rahu — and in that strange, headless inheritance, Vedic astrology finds its most paradoxical graha: the planet of loss that is also, quietly, the planet of liberation.
Ketu, like Rahu, is not a physical planet but a mathematical point — the Moon's descending node, exactly opposite Rahu in the sky at all times. Where Rahu is pure appetite with nothing to digest it, Ketu is precisely the opposite condition: a body with no head to want anything through. That single, strange image — desire without an instrument to desire with — is why classical Jyotish calls Ketu Mokṣakāraka, the significator of liberation, even though its everyday effects can feel like sudden loss, disruption or dead ends.
Where Ketu sits in a chart is where a person often arrives already strangely finished — carrying skill, detachment or disinterest that looks inherited from somewhere before this life even began. It is the graha most associated with past-life karma, spiritual practice, and the parts of a chart that feel less like ambition and more like unfinished business quietly resolving itself.
The story is the same churning of the Ocean of Milk that gives Rāhu its origin, told here from the other half. When Mohinī's discus severed Svarbhāṇu's head an instant before the stolen nectar reached his throat, two separate beings rose from a single deception: the head, touched by amṛta, became the immortal, ever-hungry Rāhu. The body — untouched by the nectar, already falling — became Ketu.
Where Rāhu kept the appetite, Ketu kept only the falling: a form with no mouth to taste victory and no throat to swallow it, granted immortality by mere proximity to something it could never actually consume. The Purāṇas treat this not as tragedy but as a strange kind of grace. A being with no way to feed its cravings is, almost by definition, already partway to renunciation — and it is this accidental detachment, born from a beheading rather than any earned wisdom, that later tradition reinterprets as Ketu's real gift: the capacity to let go of things other grahas spend a lifetime learning to release.
It is a fitting origin for the planet later astrologers would call smoky, comet-tailed, and hardest of all the Navagraha to read cleanly — because Ketu was never meant to be read as a full being at all, only as what's left when the wanting part is removed.

Like Rahu, Ketu has no universally agreed exaltation point and no sign it rules outright, since it too is a mathematical node rather than a physical body. This article follows the widely used convention that pairs it directly opposite Rahu — exalted in Sagittarius, debilitated in Gemini — though a reader should know some classical texts instead cite Scorpio as Ketu's point of strength, mirroring the Taurus-exaltation view of Rahu.
In Sagittarius, per this convention, Ketu's natural detachment meets a sign of faith and philosophy, often producing a person who arrives already deeply, almost unaccountably wise about meaning and belief, sometimes at the cost of conventional ambition. In Gemini, the sign of curiosity, communication and constant mental movement, that same detachment unsettles the very faculties Gemini relies on, and a debilitated Ketu can show up as scattered thought, disinterest in ordinary conversation, or a communication style others find hard to follow. Because Ketu holds no sign of its own, exactly like Rahu, its placement in every chart is entirely a matter of where the letting-go has been sent to work.

Because Ketu, like Rahu, is a shadow point rather than a physical significator, it carries no fixed family relationship the way the seven classical grahas do. Its portfolio instead centres on the interior and the unseen: spiritual practice, intuition and psychic sensitivity, sudden losses or endings, and the specific, almost pre-installed skills a person seems to have brought with them rather than built from scratch.
Ketu does not teach you to want less. It simply removes the part of you that could want in the first place — and calls whatever remains, freedom.
A Ketu that is well-placed — supported by benefics, in a favourable house, or active constructively during its Mahadasha — often correlates with genuine spiritual depth, sharp intuition, research ability, and an unusual, almost effortless competence in specific niche fields, as though the skill were carried over rather than freshly learned. Many charts belonging to healers, researchers and contemplatives show a strong, well-supported Ketu near the centre of the story.
An unchecked or heavily afflicted Ketu, especially conjunct malefics or isolated without benefic support, more often shows up as sudden and confusing losses, chronic disconnection from ordinary goals, health issues that resist clear diagnosis, or a diffuse anxiety about matters the person cannot quite name. Because Ketu and Rahu always sit exactly opposite each other, reading one node honestly always means reading both together as a single axis of craving and release.

No. Ketu is a mathematical point — the Moon's descending lunar node, exactly opposite Rahu at all times. It has no physical mass or light, but classical Jyotish counts it among the Navagraha because of its measurable role in eclipses and, within the tradition's framework, its psychological significance around detachment and past karma.
Ketu is called Mokshakaraka (significator of liberation) because, mythologically, it is the body left behind after the head that craved immortality was severed — a form with no instrument left to desire through. Astrologically this is read as an innate capacity for detachment, spiritual insight and letting go.
Because Ketu, like Rahu, is a shadow point rather than a physical body, classical texts differ on its point of maximum strength. This article uses the common convention of Sagittarius (opposite Rahu in Gemini), though other texts cite Scorpio instead — a genuinely unsettled question among classical authorities.
Ketu's Vimshottari Mahadasha runs 7 years and typically brings themes of detachment, spiritual growth, sudden endings, and unusual or 'inherited' skill to the forefront, shaped by Ketu's supporting placements in the birth chart.
Yes. Rahu and Ketu are always exactly 180 degrees apart in every chart, since both mark the same lunar-orbit crossing points seen from opposite ends. A careful reading of either node considers both ends of the axis together, since they describe a single, connected story of craving and release.
