All the planets in astrology(except ketu) have been provided a marana karaka sthana where the planet becomes strengthless.

If you have any planet in marana karaka, it will the highest possible negative results according to what it signifies and has to be strengthened.

For eg, Marana karaka for Rahu is 9th house because 9th house is the house of dharma,house of religion,house of spirituality and Rahu is a planet that would never like to follow dharma. In this house Rahu would not feel at ease at all even if it is exalted.

For Ketu,there is no reference found for a marana karaka sthana,but astrologers believe that Ketu in 2nd house of possession is not considered good and it is the weakest position.

Ketu represents separation in whichever house it is placed. If it is placed in 2nd house,the native would want to detach themselves from their family and material possessions and financial possession as well.

All of this might create severe problems for natives family and closed ones.

So ketu in 2nd is the worst position.
