Effects of Asta Combust planets

What is Asta combust planet ? What are the effects of Asta combust planets ?

Asta/moudya or Combustion means that the planet is in closest proximity to Sun. It is passing in the orbit closer to sun. Sun is the atma or only source of light around which all the planets revolve. Surya is Tejasvi and emits strong tejas/fire which burns everything which comes into his proximity.

Every planet has Rashmi/Rays. Whenever a planet passes into close orbit of Sun its Rashmi/Rays get subdued in front of powerful sun rays or Tejas of sun. The rays of other planets get minimized or lost in the blazing sun, they become blind. This loss of Rays causes them to loose power to give their results or makes them give erratic results because they become blind.

Moon never becomes Asta or Combust but moon as it moves closer to sun diminishes in size, shrinks in size with each passing tithi and finally Moon is totally invisible on Amavasya when it is closest to sun’s orbit.

Other planets become combust as they come into close proximity or orbit of Sun. Planets become asta or combust within range of different degrees. Fast moving planets like Venus, Mercury become combust within range of 15 degrees to Sun. Mars gets combust within 10 degrees. Slow moving planets like Saturn and Jupiter become combust within 8-10 degrees.

Rahu and Ketu do not become Combust as they are just intersection points, Ketu causes Grahana to Sun which is known as Surya grahana, As per some Scholars Saturn’s closeness to sun is bad for Sun.

Profound effects of Asta graha or combust planets can be felt when they are within 3.20 degree orbit which is the span of one navamsha, When planets are within 3.20 degree orbit to sun they will give maximum effect of combustion. For fast moving planets we can extend combustion range to 6.40 degrees which is two navamsha.

  1. Swapna says:

    Can women conceive during Shukra or guru Tara asta ( that is during moudyam period ). What are the worst days to avoid for conception.

    • astrologerashish says:

      Namaste Swapna,
      Shukra & Guru tara asta should preferably be avoided for auspicious/religious ceremonies or starting anything new.
      Avoid Tithis like Amavasya, Rikta tithis, bad yogas etc. Having said that a favorable planetary position from lagna at time of copulation is to be seen.

      Thank you.

    Thanks for hilighting hidden things in combustion of the planet. I would like to know what about the Karktwa of Jupitor in combust condition? regarding chid birth.

    • astrologerashish says:

      Namaste Suresh ji,

      Jupiter with sun is also a combination for royal birth or respect in society. Such people are in high positions or can be trustee or important people in some institution.

      With respect to children it will not give negative effects unless 5th lord, 5th house, saptamansha and jupiter is afflicted by other malefics.
