Cancer (Karka Rashi)

Cancer (Karka) is a water sign ruled by Moon. This guide uses the Vedic sidereal zodiac, with Lahiri ayanamsa for calculations. A sign can contain your Sun, Moon or another planet; your rising sign (lagna) is a separate placement.

Element: Water Ruling Planet: Moon (Chandra) Symbol: ♋

Understanding Cancer in a birth chart

Cancer occupies the 90°–120° segment of the sidereal zodiac. Its water classification and ruler Moon describe the sign; a reading also depends on which planet occupies it and which house it falls in. A sign alone does not determine a person's career, health or relationships.

Western birthday ranges use a different zodiac convention and are not a shortcut to your Vedic Moon sign. Use your birth chart to identify the placements, then choose the relevant interpretation below.

🪐 Planets in Cancer

Sun in Cancer (Friendly Sign)

friend

The Sun is well-placed in Cancer, the sign of its friend the Moon. This creates a personality that blends leadership with emotional depth, nurturing instincts, and strong attachment to home and family. The soul (Sun) is nourished by emotional security (Moon).

Moon in Cancer (Own Sign — Swakshetra)

own sign

The Moon is at home in Cancer, its own sign. This is one of the most emotionally powerful placements in Vedic astrology. The mind is deeply intuitive, nurturing, and emotionally receptive. The queen is in her own palace — emotions flow naturally, powerfully, and with great depth.

Mars in Cancer (Debilitated — Neecha)

debilitated

Mars is debilitated in Cancer — its weakest placement. The warrior planet in the nurturing sign of the Moon creates emotional volatility, suppressed anger, and a fundamental conflict between aggression and sensitivity. However, this placement gives extraordinary protective instincts and emotional courage.

Mercury in Cancer (Enemy Sign)

enemy

Mercury in Moon-ruled Cancer creates a mind that processes information through emotions and intuition rather than pure logic. The Moon is Mercury's enemy, creating tension between rational thought and emotional feeling. The intellect is colored by deep emotional sensitivity.

Jupiter in Cancer (Exalted — Uchcha)

exalted

Jupiter reaches its highest exaltation in Cancer. This is the most auspicious Jupiter placement, combining wisdom with emotional depth, compassion with abundance, and knowledge with nurturing instinct. The teacher-guru is filled with maternal love.

Venus in Cancer (Enemy Sign)

enemy

Venus in Moon-ruled Cancer creates a deeply emotional, nurturing, and domestically oriented approach to love and beauty. The Moon is Venus's enemy, stirring emotional turbulence beneath the surface of relationships and creative expression.

Saturn in Cancer (Enemy Sign)

enemy

Saturn in Moon-ruled Cancer creates deep emotional restriction and domestic challenges. The Moon is Saturn's enemy, and this placement often indicates early emotional deprivation, a difficult relationship with the mother, and the need to build emotional security through persistent inner work.

Rahu in Cancer

enemy

Rahu in Cancer creates a complex emotional landscape. The Moon's nurturing sign clashes with Rahu's materialistic, illusion-creating nature, often producing deep emotional insecurity masked by a strong outward desire for emotional connection, family, and rootedness. There is a hunger for motherly love and domestic comfort that can feel insatiable.

Ketu in Cancer

neutral

Ketu in Cancer indicates past-life mastery of nurturing, emotional care, and domestic life. You carry an innate understanding of emotions and family dynamics but may feel detached from conventional domestic roles. There can be a feeling of having "already lived" the family life, leading to a soul that seeks professional achievement and public recognition (Capricorn axis) in this incarnation.
