In this insightful guide, we’ll uncover:
- What is meant by combust in astrology?

What is Meant by Combust in Astrology?
The term “combust” means (ast, dahen, or diminished).
In astrology, a planet is said to be combust (ast or diminished) when it is too close to the Sun. The intense heat and brightness of the Sun overshadow the planet, diminishing its influence and strength.
When a planet becomes combust, it loses its ability to deliver positive outcomes effectively.
Which Planets Can Be Combust in Astrology?
In astrology, all planets can become combust, except Rahu and Ketu, as they are shadow planets and do not possess a physical form.
The list of planets that can become combust includes:
- Moon
- Mars
- Mercury
- Venus
- Jupiter
- Saturn
Among these, Venus and Mercury are often close to the Sun, but their combustion has limited effects. However, when Jupiter and Saturn become combust, they can lose their positive qualities significantly.
Why Does the Sun Cause Combustion?
In Vedic astrology, the Sun is considered the king of planets and possesses immense power. It symbolizes ego, authority, the self, and the soul. When a planet comes too close to the Sun—within a few degrees—its qualities are overshadowed by the Sun’s intense rays. Just like a spotlight dims the visibility of other lights, the Sun diminishes the effect of nearby planets.
Combustion Degree for Each Planet
Each planet becomes combust when it is within a specific distance from the Sun:
- Moon – within 12 degrees
- Mars – within 17 degrees
- Mercury – within 14 degrees (sometimes less when retrograde)
- Jupiter – within 11 degrees
- Venus – within 10 degrees
- Saturn – within 15 degrees
If a planet lies within these specified degrees from the Sun in your birth chart, it is considered combust.
How to Identify Combustion in Your Birth Chart
To determine combust planets in your horoscope, follow these steps:
- Obtain your birth chart.
- Use any astrology software and enter your birth details (date, time, and place of birth).
- Check the degrees.
- Compare the Sun’s degree with those of other planets.
- Apply the combustion rules.
For example, if the Sun is at 18 degrees in Leo and Mercury is at 22 degrees in Leo, then Mercury is considered combust.
