Ketu in Cancer (Ketu in Karka)

Ketu in Cancer is in an enemy's sign. Cancer is ruled by the Moon, and Ketu counts the Moon an enemy.

The relationship is not mutual, and that is the most useful thing on this page. Ketu regards the Moon as an enemy, but the Moon regards Ketu as neutral. The classical friendship table is asymmetric, which readers almost always assume it is not. In practice it means Ketu settles into Cancer more warily than the host intends, so the placement behaves differently depending on which of the two is the stronger graha in the chart.

Cancer is a chara water sign governing the chest and stomach, and Ketu is reckoned malefic, governing detachment, moksha, past karma, intuition. Whatever Ketu signifies — moksha, past-life skill, renunciation, occult knowledge, medicine, flags and banners — is what this rashi’s restlessness moves along.

The Dignity, Stated Precisely

• In Cancer: in an enemy's sign.
• Ketu’s own sign: None — Ketu co-lords Scorpio and is said to act as its dispositor. The standard scheme gives the nodes no rashi of their own; what is quoted is a co-lordship, and it is not universally accepted.
• Exalted in: Scorpio by the most common reckoning; Sagittarius in others.
• Debilitated in: Taurus by the same reckoning; Gemini in others.
• Moolatrikona: Not assigned in the standard system.
• Cancer’s lord: Moon. Cancer exalts Jupiter at 5° and debilitates Mars at 28°.

One honest caveat, because it applies to Ketu specifically. The standard exaltation table covers the seven grahas and does not assign the nodes a dignity at all; what is quoted above is the most common reckoning, and other traditions give a different sign. The rashi tables on this site record only the seven, which is why they and the graha tables disagree here and nowhere else. Treat a nodal “exaltation” as one school’s convention rather than a settled fact, and weigh the node by house, dispositor and dasha instead.

What Ketu Aspects From Cancer

Ketu is given no aspect of its own by the classical texts, and the traditions that do assign one do not agree with each other — many lend it the aspects of its dispositor, others none at all. So this page does not print a list of signs Ketu aspects from Cancer: doing so would be asserting a convention as a fact. What Ketu in Cancer does do is take on the character of its dispositor, the Moon, and act through wherever the Moon sits in the chart. That is the reading to make, and it needs the whole chart.

The Axis: Ketu in Cancer Means Rahu in Capricorn

The nodes are not two independent bodies. They are the two ends of one line — the intersections of the Moon’s orbit with the ecliptic — and they are always exactly six rashis apart. So Ketu in Cancer is not a placement you can read on its own: it fixes Rahu in Capricorn, ruled by Saturn, and the axis has to be read as a pair.

That gives this particular axis two dispositors: the Moon for Ketu and Saturn for Rahu. Here they are different grahas, so the two ends of the axis answer to different masters and can be in very unequal condition. Whichever end carries the stronger dispositor tends to be where the axis actually delivers, and the classical reading is that Ketu amplifies while Rahu empties — the same axis produces excess at one end and detachment at the other.

For the other end of this axis, see Rahu in Capricorn.

How Far Cancer Is From Ketu’s Own Ground

A graha is read partly by how far it has been displaced from the rashi it owns, and that distance is simple counting. Counting inclusively from Scorpio (a co-lordship rather than an ownership, as noted above), Cancer falls as follows:

• 9th from Scorpio — a trine, the easiest of the distances.
• 9th from Scorpio, the sign of its exaltation (on the commoner reckoning — this one is disputed) — a trine, the easiest of the distances.
• 3rd from Taurus, the sign of its fall — a 3/11, the upachaya pairing.
• Opposite Cancer stands Capricorn, ruled by Saturn — the rashi Ketu faces from here, and therefore the one it aspects whatever else it does or does not aspect.

The Company Ketu Keeps in Cancer

Dignity runs in both directions, and the rashi has its own roster. Cancer runs from 90°00′ to 120°00′ of sidereal longitude — the arc the Sun crosses about Jul 17 – Aug 16 — faces north, is classed female, and as a water sign is of the Brahmin varna. Within those thirty degrees:

• Ruled by Moon.
• Exalts Jupiter at 5° — not Ketu, so the strongest single degree of Cancer is not Ketu’s.
• Debilitates Mars at 28°, a different graha from Ketu.
• Holds no moolatrikona. Cancer contains no graha’s moolatrikona stretch, so there is no privileged arc within it.

So Ketu shares Cancer with both an exaltation degree and a debilitation degree belonging to other grahas. A graha sitting close to either point is read against it, which is a reason the exact degree matters more in Cancer than in a sign carrying neither. Cancer’s own traits — nurturing, intuitive, emotional, protective, loyal — are the register in which detachment, moksha, past karma, intuition gets expressed when Ketu sits here.

The Nine Padas Ketu Crosses in Cancer

A rashi is thirty degrees and a pada is three degrees twenty minutes, so every sign holds exactly nine padas — never a round number of nakshatras. Cancer holds 3 nakshatras in whole or in part: Punarvasu (pada 4), Pushya and Ashlesha.

Ketu rules Ashwini, Magha, Mula, and none of them falls in Cancer. So across all thirty degrees there is no stretch where Ketu has nakshatra-level ownership to fall back on; the whole sign is read through the Moon, and through what the Moon makes of a guest it counts neutral. The nakshatra lords it does cross here are Jupiter, Saturn, Mercury.

When Ketu Is Actually in Cancer

This is the part of the page that is not in a textbook. Computed from the DE421 sidereal ephemeris, Ketu occupies Cancer for one stretch inside 2026 and 2027:

• 5 December 2026 to 31 December 2027, entered in retrograde motion. This stretch is still running when the computed window ends, so the exit falls after 2027 and no date for it is printed here.

Dates, not clock times, and deliberately so. Ketu crosses this boundary at well under a tenth of a degree per day, which means the exact instant of the ingress depends on which ayanamsa a table uses rather than on the solar system. The day is solid; a minute would be a decoration.

Reading Ketu in Cancer

Ketu signifies moksha, past-life skill, renunciation, occult knowledge, medicine, flags and banners. In Cancer those significations are filtered through a chara water sign ruled by the Moon, and the dignity above says how much support they get in the process. In an enemy’s sign they meet resistance from the host, and the results tend to arrive late or in a form the native did not ask for.

This is not a prediction, and it cannot be one: the house Cancer occupies from the ascendant, which of the nine padas above holds the graha, and the running dasha all change the answer. Ketu is reckoned malefic and is a shadow graha with no disc of its own, and it gains in the 3rd, 6th, 11th and 12th while it struggles in the 1st, 2nd, 4th, 5th and 7th — so Ketu in Cancer is a different placement in each of them. Under Kaal Purush Cancer is the 4th bhava, so Ketu in the 4th house is the same pairing read from the bhava side, with the Cancer transit dated for each of the twelve ascendants.

For what Ketu does when strong and when afflicted, its 7-year mahadasha, and the full remedy set, see the Ketu (Ketu) page. The short form: Ketu’s day is Tuesday, its gemstone is Cat's Eye (Lehsunia), its mantra is Om Kem Ketave Namah, and its deities are Ganesha, and Bhairava.
