A conjunction (yuti) is two or more planets in the same sign. It is one of the first things anyone notices in a chart, because it is easy to see and because two planets together are read as a blend: each lends the other something and each also colours it. The Sun and the Moon are in the most conjunctions people ask about, since they are the two lights and the two planets most closely tied to who you are. This library covers all thirty-five pairs of the nine grahas: the fifteen with the Sun or the Moon first, then the twenty among the other planets.
Everything here describes tendencies. A conjunction shows a theme in a chart, and how it plays out depends on the sign, the house, the strength of both planets, aspects from others and the dashas. No pair on this page “will” cause anything, and none needs fear.
The pairs with the Sun
The Sun is the soul, the will and authority. Other planets that sit close to it are sometimes dimmed by the glare, which is called combustion (see below).
- Sun and Moon: a birth near the new moon.
- Sun and Mars: two fires, courage and leadership.
- Sun and Mercury: the most common pair, Budhaditya.
- Sun and Jupiter: authority with wisdom.
- Sun and Venus: presence and taste.
- Sun and Saturn: father and son, effort and patience.
- Sun and Rahu: Grahan Yoga, ambition and authority.
- Sun and Ketu: a self turned inward.
The pairs with the Moon
The Moon is the mind, the mood and the sense of security. Its strength depends on its phase, so a bright waxing Moon and a dark waning one read differently in every pairing.
- Moon and Mars: Chandra Mangala, feeling into action.
- Moon and Mercury: the quick, restless mind.
- Moon and Jupiter: the generous heart and Gaja Kesari.
- Moon and Venus: comfort, taste and tenderness.
- Moon and Saturn: feeling under discipline, Vish Yoga.
- Moon and Rahu: Chandra Grahan Yoga, the absorbent mind.
- Moon and Ketu: the intuitive, inward mind.
The pairs without the Sun or the Moon
Rahu and Ketu are always exactly opposite each other, so they never share a sign and there is no page for that pair; when a planet is with one node, the other node sits in the 7th sign from it.
- Mars and Mercury: the sharp, quick mind.
- Mars and Jupiter: courage with principle, Guru Mangala Yoga.
- Mars and Venus: passion, taste and drive.
- Mars and Saturn: the accelerator and the brake.
- Mars and Rahu: Angarak Yoga, intense drive.
- Mars and Ketu: focused, fearless, detached.
- Mercury and Jupiter: the scholar’s mind.
- Mercury and Venus: wit and charm, Lakshmi Narayana Yoga.
- Mercury and Saturn: the careful, disciplined mind.
- Mercury and Rahu: the inventive, restless mind.
- Mercury and Ketu: the intuitive researcher.
- Jupiter and Venus: the two teachers, wisdom with taste.
- Jupiter and Saturn: the twenty-year Great Conjunction.
- Jupiter and Rahu: Guru Chandala Yoga, the questioning mind.
- Jupiter and Ketu: the seeker’s pairing.
- Venus and Saturn: love under discipline.
- Venus and Rahu: glamour, desire and novelty.
- Venus and Ketu: refined taste, quiet detachment.
- Saturn and Rahu: Shrapit Yoga, pressure and stamina.
- Saturn and Ketu: the solitary craftsperson.
How to read any conjunction
- Check it is real. The planets must share a sidereal sign. A tropical chart can put them together or apart where the sidereal chart does the opposite. For the Moon, birth time matters, because it changes sign every two and a quarter days.
- Measure the gap. A conjunction within a few degrees blends the two natures completely. A wide one in the same sign blends them loosely.
- Check each planet’s dignity. A planet is strong in its own sign or its sign of exaltation, and weak in its sign of debilitation.
- Look at the house. The same pair reads differently in the 1st, the 6th and the 10th. Planets also gain directional strength in particular houses: the Sun and Mars in the 10th, the Moon and Venus in the 4th, Jupiter and Mercury in the 1st and Saturn in the 7th.
- Look at the friendships. The classical friendship table in Brihat Parashara Hora Shastra says which planets get on. It is not symmetrical, and it describes natures, not outcomes.
- Add the dashas. A conjunction speaks mainly in the periods of the planets involved.
Combustion
A planet very close to the Sun is called combust (asta), and many teachers read it as weakened, with its independent results absorbed into the Sun’s. Others say some planets, Mercury and the Sun’s friends in particular, lose little. The orbs the site’s chart engine uses are these:
| Planet | Combust within |
|---|---|
| Moon | 12 degrees |
| Mars | 17 degrees |
| Mercury | 14 degrees (12 when retrograde) |
| Jupiter | 11 degrees |
| Venus | 10 degrees (8 when retrograde) |
| Saturn | 15 degrees |
Orbs differ between authorities, so a borderline case can read differently elsewhere. Rahu and Ketu are nodes, not bodies, and are not treated as combust. Their closeness to the Sun or Moon is read as the gap between them.
A note on sources
The dignity, friendship and aspect rules used throughout come from the classical framework set out in Brihat Parashara Hora Shastra. Pair-by-pair results are found in later compilations and commentaries, and the wording varies from book to book, so these guides give the reading most teachers share and say where views differ. Where a yoga name is a later or regional tradition, the page says so, and none of the guides gives a verse number that could not be checked.

Find your conjunctions
The planet position calculator places every planet by sign, degree and house from your birth details. The yoga finders for Budhaditya and Gaja Kesari test those yogas directly, the Kaal Sarp calculator tests the node axis, and the Pancha Mahapurusha finder checks the planets in their own or exalted signs in kendras.
Frequently asked questions
↳ What is a conjunction in Vedic astrology?
It is two or more planets in the same sidereal sign. Tradition reads them as blending their natures, with the result depending on dignity, house, closeness and the dashas.
↳ Is a conjunction with the Sun always bad?
No. Some planets close to the Sun are read as weakened, which is called combustion, but the Sun's friends lose little and many people with these pairs do well. The gap in degrees and the rest of the chart count more than the label.
↳ How close must planets be to count as conjunct?
In the same sign is the basic rule. A closer gap, within a few degrees, is a stronger blend, and a wide gap in the same sign is looser.
↳ Do the Moon conjunctions depend on birth time?
Yes. The Moon changes sign about every two and a quarter days, so a birth near a sign change can put the Moon in either sign. An exact birth time settles it.
↳ Are the Grahan yogas something to fear?
No. The Sun or Moon with Rahu is called Grahan Yoga after the eclipse myth, but it is a later tradition, and it describes a theme about ambition or an active mind. Many accomplished people have it.
