Ketu
Also written the south lunar node · the dragon’s tail
Ketu is the south node of the moon — the point exactly opposite Rahu, and the other place eclipses occur. Like Rahu it is a shadow graha, but its character is the reverse: where Rahu hungers, Ketu releases.
It signifies detachment, spirituality and moksha (liberation), the things we are done wanting; also instinctive, past-life skill that comes without effort, and the sense of incompleteness that turns a person inward.

Ketu rules the nakshatras Ashwini, Magha and Mula. The node convention here is the mean node: Ketu = Rahu + 180°.
