Rahu - Ketu

Rahu is the Dragons Head and Ketu is the Dragons Tail.While all planets

move anti–clockwise, Rahu and Ketu move clockwise through the skies.
Rahu and Ketu are always in the 7th house from the other i.e.: 180
degrees apart or in other words, in perfect opposition. They always move
in synchronism to keep the 180 degrees difference between them.
