Weak planets do not provide good results in the areas ruled by the planet and are more susceptible to affliction. The following factors that contribute to planetary weakness:
- Placement in one of the malefic houses - 6th, 8th or 12th (unless it is it's own 'Mooltrikona' sign).
- Placement in it's sign of debilitation.
- Placement in the first or last 5 degrees of a sign.
- Placement in it's debilitated sign in the ninth division of the natal chart.
- If it’s depositor is weak, i.e. it occupies the 'Mooltrikona' sign of a weak planet.
- If with respect to the Moon, it is within 72 degrees either side of the Sun.
- If it is closely accepted by any functional malefic planet.
- If the most effective point of the house that it occupies is closely afflicted by a functional malefic planet.
- If the most effective point of it's 'Mooltrikona' sign is closely afflicted by a functional malefic planet.
The ‘Close Afflictions’ above refer to an orb of one degree or less.
- An affliction is caused by a functional malefic planet, which is a planet ruling the 6th, 8th or 12th houses.
- A weak planet can be afflicted by an orb up to 5 degrees from a functional malefic planet. However, a strong planet is only afflicted by an orb of one degree or less.
An exception applies when the aspect is from:
- The most malefic planet, an aspect from a functional malefic placed in the 6th, 8th or 12th houses.
- A conjunction with Rahu or Ketu (the Rahu-Ketu axis).
- A functional malefic that is also afflicted.
- More than one functional malefic at the same time.
