Combust Planets in Birth Chart and Today — Every Asta Period, With Its Effect

Combust planets today: No planet from Mercury to Saturn is combust today (24 September 2026). Venus (Shukra) is combust in 2026: 26 Nov 2025 to 17 Feb 2026; 19 Oct 2026 to 29 Oct 2026. Jupiter (Guru) is combust in 2026: 14 Jul 2026 to 13 Aug 2026.

A planet is combust - asta in Sanskrit, literally "set" - when it comes so close to the Sun that it disappears in the Sun's glare. In the sky this is a real event: Venus vanishes as a morning or evening star for weeks, Jupiter drops out of view before reappearing on the other side of the Sun. Jyotish reads this invisibility as the planet losing its strength for a while; its significations are "burnt" by the Sun.

Each planet has its own distance, or orb, within which it is considered combust. Classical texts give the values below; Mercury and Venus have a smaller orb when retrograde. The Moon is combust for a day or two around every new moon, which is why amavasya is treated as a low day for the mind.

Combust planets in the birth chart are not "bad", but their results come later and need effort. A combust planet's significations - what it rules and the houses it owns - ask for conscious care. Add your date, time and place of birth to the form to see which of your planets were combust, how far each was from the Sun, and what it means.

The most practical use of combustion is in muhurat. When Jupiter (Guru) or Venus (Shukra) is combust, the tradition does not fix weddings, engagements, griha pravesh, mundan or the start of a new venture. Jupiter blesses marriage and Venus rules it, so their "setting" is read as a pause on these beginnings. Many families also wait a few days after the planet reappears (uday) before fixing a date.

That is why wedding seasons in India have gaps each year: the Venus combust dates and Jupiter combust dates in the table above are exactly the periods when priests do not give marriage muhurats. If you are planning a wedding, check these dates first, then use the Shubh Muhurat calculator for a date that suits your chart.

Mercury combust periods are shorter and more frequent; they matter mainly for contracts and business beginnings. Mars and Saturn combust periods are read as slow times for property and career matters.

1. Distance from the Sun. The angular distance of each planet from the Sun is computed with the Swiss Ephemeris; if it is inside that planet's orb (smaller when retrograde for Mercury and Venus), the planet is combust.

2. Periods found. The day a planet enters and leaves its orb is found for the chosen year, giving every combust period with its length - including the Guru asta and Shukra asta dates.

3. Your chart. With your birth details, the distance of each planet from the Sun in your chart is shown against its orb, with the effect of every combust planet.

Combustion and retrograde motion are often confused because both change how a planet behaves, and they sometimes happen together. Combustion is about distance from the Sun; retrograde motion is about the planet's apparent direction. The table sets them side by side.

This is why classical texts give Mercury and Venus a smaller orb when they are retrograde: a retrograde planet is closer to the Earth and brighter, so it is held to be harder to "burn". For every retrograde period of the year, see the retrograde planets page linked below.

Mercury never moves more than about 28 degrees from the Sun, so in a large share of birth charts it sits in the same sign as the Sun. That combination is the celebrated Budh-Aditya yoga, linked to intelligence, good speech and success in education and business. How can Mercury be combust and still give a good yoga?

Most astrologers read it this way: the yoga works fully when Mercury is in the same sign as the Sun but outside its combustion orb - more than 14 degrees away (12 if retrograde). When Mercury is deeply combust, within a few degrees, the yoga still exists but its fruits come after effort, and the person may think faster than they speak. The result shows Mercury's exact distance from the Sun in your chart, so you can see which case applies.

A similar softer reading is often given to Mercury generally: because it is combust so often, many traditions treat a combust Mercury more lightly than a combust Jupiter or Venus.

A combust planet "rises" again - uday - when it moves out of the Sun's orb and becomes visible at dawn or dusk. For Jupiter and Venus the tradition adds a short waiting period, often three days, sometimes described as the planet's childhood (bal) as it rises, and a similar old-age (vriddha) period just before it sets. Many priests avoid fixing weddings in these edge days too, so the practical gap in the wedding calendar is a little longer than the combust dates alone.

When you plan a wedding, engagement or griha pravesh, start from the table above: find the Guru asta and Shukra asta dates for the year, leave a few days on either side, and then look for a date that also avoids kharmas and suits both charts. The Shubh Muhurat calculator handles the chart part; this page gives the asta window.

For combust planets in your birth chart, uday has a gentler meaning: the planet's matters tend to improve in its own dasha or antardasha later in life, once you have put in the effort it asks for.
