Rahu and Ketu are the lunar nodes, the two points where the Moon orbit crosses the path of the Sun. They are not solid bodies, which is why Vedic astrology calls them shadow planets. Their transit behaves unlike any planet: they always move backward, they always sit exactly opposite each other, and they cross about one sign every 1.5 years. Together they form an axis that quietly reshapes desire and detachment in your chart. This page covers how the nodes transit and why eclipses cluster around them.
Always retrograde, always opposite
The nodes have two unusual habits. First, they are always retrograde, meaning they move backward through the zodiac rather than forward like the planets. Second, they are always exactly opposite each other, six signs apart. If Rahu transits Aries, Ketu transits Libra at the same time. Because of this, you never read one node alone; you read the whole axis they create across two opposite houses of your chart. Their backward motion gives node transits a distinct, unsettling quality.
About 1.5 years per sign
Rahu and Ketu transit one sign in roughly 1.5 years, completing the full zodiac in about eighteen years. That makes them slower than Jupiter but faster than Saturn, so a node transit is a medium-length season that reshapes two areas of life at once. As the axis shifts every 1.5 years, the pair of houses under pressure changes too. Watching where Rahu and Ketu currently sit relative to your Moon shows which paired themes are being stirred up in the present.
Rahu desire, Ketu detachment
The two nodes pull in opposite directions, which is the heart of how the axis works. Rahu signifies craving, ambition, and the hunger to acquire, so the house it transits often becomes a place of intense desire, sudden growth, and sometimes confusion or disruption as you chase something new. Ketu signifies detachment, doubt, and letting go, so the opposite house it transits can feel emptied out or strangely uninteresting. The axis asks you to grow in one area while releasing your grip on the other.
Eclipses and the nodes
Eclipses are the most visible sign of the nodes at work. A solar or lunar eclipse can only happen when the Sun and Moon line up close to the node axis, which is exactly why these points are tied to eclipses in tradition. When an eclipse falls near a sensitive point in your chart, astrologers read it as a marker of change along the Rahu-Ketu themes. Read this calmly, not fearfully: an eclipse highlights where the axis is active, it does not predict misfortune by itself.
Key takeaways
- Rahu and Ketu are the lunar nodes, shadow planets formed where the Moon path crosses the Sun path.
- The nodes are always retrograde and always exactly opposite each other, six signs apart.
- They transit one sign in about 1.5 years, completing the zodiac in roughly eighteen years.
- Rahu brings desire, ambition, and disruption; Ketu brings detachment and letting go, across an axis.
- Eclipses occur near the nodes; they mark where change is active rather than predicting misfortune.
