The idol of the Ketu should be made using brass. Ketu is described in several forms in different scriptures. It is of smoky colour with a pair of arms, one holding a club and another in a blessing posture and showing riding on a donkey having a steady speed.
Ketu should be worshipped with the flowers and clothes of the colours of the idol and with fragrance, sticks, Deepa, giving oblations, Dhupa, Guggul, etc. The metal of the idol of the planet and the food dear to him as signified by the planet are donated in charity with full devoutness for the alleviation of the affliction.
Maharishi Parashara said that the Mantra of Ketu should be recited seventeen thousand times.
The type of wood to be used for Havan of Ketu is Kusha. The Havana Samagri duly mixed with honey, ghee, curd, or milk is offered as oblations into the sacred fire and amidst chanting of the Mantras 108 or 28 times, the Havana should be performed.
After that Brahmins should be fed. Rice cooked with pulses (khichri) is prescribed for Ketu Shanti. After the worship Dakshina should be given as per shraddha of yajmana (person performing the Havan) and satisfaction of Brahmins.

Astrology may be one of the insights that our ancient Rishi-Munis might have got as part of their self-seeking or Tapasya. We should be thankful to all the people who translated that insight for understanding the common man. We should use Astrology as a tool to improve our lives and also to make the world a better and kinder place to live in.
