I am Ketu conjunct Moon myself. Star and Ketu ruled lagna star, in Rahu mahadasha. The effects of Rahu and Ketu depend most on what surrounds them in all respects like other planets. They are more reactive than anything though- they react and attack rather than build, unless what they are building is foreign to the place and times, new, different, a growth, a revolution, an alteration for either creative better, taking on new and better foreign ideas say, or for the worse, spraypaint and poison, revolution and killing. The house, sign and conjunctions are the greatest and main things to watch.
Nodal conjunctions are important.
The houses they reside in is the most key, then the sign, then the conjunctions, perhaps in that or other order. This is my understanding. For example, Rahu in the sixth connects him with the persons and things the sixth rules. Ketu in the 10th connects Ketu with 10th house significations. The sign colors the behavior and conjuncted planets become affected.
