When a planet is placed too close to the Sun in the horoscope, it’s considered “combustion”. However, the position of the planet in relation to the Sun shows different results.

1/ Degree of combustion

• Venus gets combusted within 8 degrees
• Mercury gets combusted within 12 degrees
• Jupiter gets combusted within 15 degrees
• Saturn gets combusted within 15 degrees
• Mars gets combusted within 17 degrees

2/ General effect

• Planets won’t be able to deliver their full result, both favorable and unfavorable, which is considered “burned by the Sun.”
• The Sun is well placed, lord of good houses, and burned benefic planets. The result is still good.
• The Sun is the ruler of the 6th, 8th, or 12th house, and not well placed, indicating conflicts, outbursts.

Planetary significations:

- Mars: Anger, Willpower, Siblings

- Mercury: Intellect, Memory

- Venus: Marriage, Money

- Jupiter: Children, Thinking Capacity

- Saturn: Career, Hardwork

3/ What is combustion?

It’s when looking at the planet from Earth. That planet goes behind the Sun. They appear to be close to each other on a 2D horoscope. In reality, the planet is slowly becoming temporarily invisible to the eyes because the Sun is too bright. That's why we consider the combust planet does not give a full result.

• 3.1/ In this case, Mercury will appear in the same house as the Sun on 31.8.2025. Degree-wise, it’s before the Sun and approaching the Sun. It’s not a favorable combustion.

Imagine Mercury as a Kid. The kid is trying to hide behind the father now. That suggests something must scare him, so that he has to search for protection. Maybe he didn’t do the homework, which makes the mother really angry, for example. That means one makes mistakes regarding the signification of the planet and its lordship.

• Mercury represents the communication skill. It’s clearly affected in combustion. If The Kid (Mercury) is going towards and behind the Father (Sun) due to some problems, then he does not talk much. It’s logic. In other words, with this combination in a horoscope, the native might appear as an introvert.

With this combustion, when the planet is approaching the Sun, the closer it is, the worse the situation/mistake will be. Surely, the benefit of this placement is that the Kid gets help from the Father (real father, father figure, or authority), always. But how long and how much? That depends on the strength of the Sun in relation to the combust planet and other placements in the horoscope and Dasa. If everything went well, one would even be successful, but the impact is still undeniable.

• 3.2/ When a person is born on 24.09.2025, this combustion is more beneficial

The combust Mercury is placed after the Sun in the horoscope. The Kid (Mercury) is leaving the Father (Sun). He had “the private lesson” from the Father. He is smarter now and confidently faces the challenge himself. 

• This combination still indicates an introverted personality, but the native has the knowledge from the Father (Sun) and the discipline(after the private lesson) to correct the mistakes by himself and avoid repeating them.

4/ Example

This Venus in this chart has a very close combustion degree to the Sun, aspect by Jupiter.

• The native is super-rich and achieved success during the Jupiter Dasa. That’s the positive aspect of combust Venus. Got support from father-figured and authority.
• Being combust before the Sun (degree-wise) is, however, not ideal. Married life is completely disturbed. Multiple marriages. Until the last breath, the native still wants to get divorced. The mistake is repeated over and over again.

5/ Summary

When a planet is combust, it’s not the same as when it’s conjunct with the Sun. The outcome will be very different depending on the position of the planets, the house placement, lordship, and the Dasa. There are no rules that cover all of those aspects. Every chart must be checked carefully.

For other examples with combust planets placed after the sun degree-wise, you can easily find them in famous and wise people’s horoscopes (Einstein, Swami Vivekananda, etc). And maybe you’re the next.
