the sun burns things, and only the sun

a graha too close to the sun is called astangata, burnt, and treated as having lost its own voice. here are the orbs for each one, why mercury spends about half its life inside them, and what the condition actually changes.

OCTOBER 4, 2026 · 9 MIN READ

there is exactly one graha in the system that can damage another just by standing near it, and it is the one everybody thinks of as the warm centre of the chart.

a graha too close to the sun is called astangata, burnt. the reasoning is observational and completely literal: a planet near the sun is invisible, lost in the glare, and the tradition treated a graha u cannot see as a graha that cannot speak for itself.

here are the orbs, how common each one actually is, and what the condition genuinely changes.

the short version

astangata means set or burnt. a graha within a set number of degrees of the sun loses its independent voice.
the sun causes it and can never suffer it. rahu and ketu are unaffected, having no body to hide.
orbs, commonly given: moon 12, mars 17, mercury 14, jupiter 11, venus 10, saturn 15.
mercury is combust about half the time, because its whole range is 28 degrees and the orb is 14.
it does not destroy the graha. the significations remain, absorbed into the sun's agenda.
cazimi is a western idea, not a vedic one. it should not be quoted as classical.

quick facts

Sanskrit: Astangata, or asta. Meaning set, as in a star that has set.
Cause: Proximity to the Sun in zodiacal longitude.
Immune: The Sun itself, and Rahu and Ketu.
Most affected: Mercury, then Venus. Both are leashed near the Sun.
Least affected: Jupiter, with the narrowest orb and a full range of positions.
Retrograde adjustment: Mercury 12 and Venus 8 in most sources.
Not the same as: Cazimi, which is Western and means the opposite.
Variation: Classical sources differ by a degree or two. It is a convention.

what combustion actually is

A graha within a certain number of degrees of the Sun is called astangata, burnt or set. The classical reading is that the graha's independent voice is drowned out, in the same way a star is invisible in daylight even though it is still there.

the observational basis is unusually clean. a planet close to the sun in the sky cannot be seen. venus disappears for weeks around its conjunction with the sun. mercury is barely ever visible at all. the tradition looked at that and drew a straightforward conclusion.

and the word matters. asta means set, as in sunset. the graha has not been destroyed, it has gone below the horizon of what can be perceived. that distinction is the whole difference between a useful reading and a frightening one.

note also what combustion is measured on: zodiacal longitude, not distance in space. a graha can be hundreds of millions of kilometres from the sun and still be combust, because what is being measured is the angle from where we are standing.

the orbs, and how common each one is

Each graha has its own combustion orb. Because Mercury and Venus are locked near the Sun and the outer grahas are not, the frequency varies enormously between them.

graha	orb	retrograde orb	roughly how often combust
Mercury	14°	12°	very often. about half the time
Venus	10°	8°	often. roughly one chart in five
Moon	12°	—	about 7% of the time. near amavasya
Mars	17°	—	roughly 9%
Saturn	15°	—	roughly 8%
Jupiter	11°	—	roughly 6%. the least combustible
Rahu, Ketu	—	—	never. no body to hide

the frequency column is the part almost nobody supplies, and it is what turns the table from trivia into something usable.

for the outer grahas the maths is simple: the burn zone is the orb either side of the sun, so mars at 17 degrees covers 34 of the 360 available, which is a bit under ten percent. jupiter's 11 degrees covers 22, about six percent.

for mercury and venus the maths is completely different, because they cannot use the full 360. that is the next section.

why mercury spends half its life burnt

Mercury can never appear more than about 28 degrees from the Sun, so its entire possible range is 56 degrees wide. The combustion orb is 14 degrees either side, which is 28 of those 56. Half of everywhere Mercury can be is inside the burn radius.

this is the cleanest example of why a label's frequency has to come before its meaning.

the real distribution is not perfectly uniform, because mercury lingers near its greatest elongations and moves quickly through the middle. so the true figure is somewhat under half. it remains, by a wide margin, the most common planetary condition anybody will ever be told about.

venus is the same shape at a wider radius: about 47 degrees of maximum elongation, a 94 degree range, and a 20 degree burn zone. roughly one in five.

and this interacts with something worth noticing. budhaditya yoga, mercury with the sun, is celebrated as intelligence joined to recognition. but if mercury is inside 14 degrees, the same conjunction is usually read as burnt instead. the two readings sit on the same degrees, and which one u are handed often depends on who is talking.

what it changes, and what it does not

Combustion is read as a loss of independent voice, not a loss of function. The graha still signifies everything it always signified. What changes is that those significations run through the Sun's agenda rather than on their own terms.

graha combust	the usual reading
Mercury	the mind fused to the sense of self. thinks in first person, argues from identity rather than analysis
Venus	desire routed through ego and status. what u want and who u want to be are hard to separate
Moon	emotional life absorbed into self-image. also weak by paksha bala. see below
Mars	drive that only fires for personal stakes. hard to mobilise for anyone else's cause
Jupiter	belief and identity difficult to separate. conviction held personally rather than examined
Saturn	discipline applied to the self rather than imposed by the world. self-critical

read down that column and a pattern shows: every one of them is a fusion with the self, not an absence. that is a much more accurate and much more useful description than "damaged".

and in dasha terms, practitioners generally read a combust graha's period as one where its significations arrive through solar themes: authority, recognition, position, the father. the graha still delivers. it just does not get to speak in its own voice while doing so.

the combust moon takes two hits

A Moon within 12 degrees of the Sun is close to new, so it is simultaneously combust and at its weakest by paksha bala, the fortnight strength. It is the only graha that can be penalised twice by the same geometry.

the two rules are separate and they happen to coincide. paksha bala measures the moon's distance from the sun as brightness, and combustion measures the same distance as invisibility. near amavasya, both are at their minimum.

this is why the tithi someone was born on carries real information, and it is one of the few places where the panchang and the birth chart touch each other directly.

the honest reading is sensitivity, not damage. a mind running on less light is a mind that takes in more and holds it longer. plenty of very perceptive people were born near a new moon, and describing that as a defect is both unkind and wrong.

cazimi is not a vedic idea

Cazimi describes a planet within about 17 arcminutes of the Sun, treated in Western astrology as strengthened rather than burnt. It is not part of classical Vedic astrology and should not be quoted as though it were.

the word comes through arabic from the greek, and the image is a planet in the heart of the sun rather than beside it. it is a real and interesting idea in the tradition it belongs to.

it is also increasingly quoted in indian astrology content as though it were classical, usually to soften a combustion. that is worth flagging, not because the idea is bad, but because attributing it to the wrong tradition makes it impossible for a reader to check anything.

the same applies to shadow periods. borrowed ideas are fine. borrowed ideas presented as ancient jyotish are not.

checking ur own chart

Take the longitude of the Sun and the longitude of the graha. If the difference is smaller than that graha's orb, it is combust. Any chart showing exact degrees lets you do this in about thirty seconds.

worked example. sun at 18 degrees kanya, mercury at 27 degrees kanya. the difference is 9 degrees, and mercury's orb is 14. combust.

second example. sun at 18 degrees kanya, venus at 2 degrees tula. that is 12 degrees apart across the sign boundary, and venus's orb is 10. not combust, though close.

two things to be careful about. work in absolute longitude across sign boundaries rather than within a sign, and check whether the graha is retrograde, since mercury and venus use narrower orbs when they are.

and once u have the answer, put it where it belongs in the reading order: after dignity, before yogas. the twelve step order has the full sequence.

myths, one at a time

A combust planet is destroyed.

It loses its independent voice, not its significations. The classical word means set, as in a star below the horizon, not burnt away.

Combustion is rare and serious.

Roughly half of all charts have a combust mercury. It is the most common planetary condition in the system.

Cazimi is the vedic exception to combustion.

Cazimi is a Western concept. It is not in the classical Vedic material and quoting it as such makes the reading uncheckable.

The Sun can be combust too.

It causes combustion and cannot suffer it. Rahu and Ketu are also immune, having no body to be hidden.

Budhaditya yoga and a combust mercury are different placements.

Very often they are the same degrees described two ways. Which reading u get frequently depends on what the reader wants to say.

All texts agree on the orbs.

They differ by a degree or two, and practitioners handle retrograde adjustments differently. Ask which set is being used.

faq

what is combustion in vedic astrology?

astangata, meaning set or burnt. a graha within a certain number of degrees of the sun is treated as having lost its independent voice, drowned out the way a star is drowned out by daylight.

what are the combustion orbs?

commonly given as moon 12 degrees, mars 17, mercury 14 and 12 when retrograde, jupiter 11, venus 10 and 8 when retrograde, saturn 15. texts differ slightly, so check which set a reading is using.

can the sun be combust?

no. the sun is the only graha that causes combustion and the only one that can never suffer it. rahu and ketu are also unaffected, because they have no body to be hidden.

why is mercury combust so often?

because mercury never appears more than about 28 degrees from the sun, and the combustion orb is 14 degrees. half of its entire possible range sits inside the burn radius.

does combustion destroy a planet?

no. the classical reading is that the graha loses its independent voice, not its significations. it is absorbed into the sun's agenda rather than removed from the chart.

is a combust planet in my birth chart a problem?

it is a condition to note, not a verdict. combustion is very common for mercury and venus, and what matters far more is what the graha rules for ur lagna and where it sits.

what is cazimi?

a western concept where a planet within about 17 arcminutes of the sun is considered strengthened rather than burnt. it is not part of classical vedic astrology and should not be presented as though it were.

does combustion affect dasha results?

practitioners generally read a combust graha's period as one where its significations run through the sun's themes: authority, the self, recognition and the father, rather than independently.

which planets combust least often?

jupiter, with an 11 degree orb and a full 360 degrees of possible positions, so roughly six percent of the time. saturn and mars are similar. venus and mercury are the frequent ones because they are leashed to the sun.

how do i check if a planet is combust in my chart?

take the difference in degrees between that graha and the sun. if it is less than the orb for that graha, it is combust. any chart that shows exact degrees lets u check it in a few seconds.

is a combust moon significant?

a moon within 12 degrees of the sun is near new, so it is both combust and at its weakest by paksha bala. it takes both hits at once, which is why the tithi u were born on carries real information.

do all texts agree on the orbs?

no. the figures above are the most widely used, but classical sources vary by a degree or two and some practitioners adjust for retrograde motion differently. it is a convention, not a constant.
