What is Rahu and Ketu
January 20, 2019
What is Rahu (North Node) and Ketu (South Node)
Today is the complete Lunar eclipse day so its great day to start a series on Rahu and Ketu
Rahu and Ketu are not actual physical planets, they are even referred as “chhaya grah” or shadow planets. However they are actual mathematical points whose motion can be calculated. So lets see how the Rahu and Ketu (mathematical points) are made –
Rahu and Ketu are created due to relative motion of Sun, Moon and Earth.
Earth revolves around Sun in elliptical orbit. That motion creates a Plane of Earth and Sun movement. Please see pic 1 and yellow highlight plane.
Moon revolves around Earth in another smaller ellipse
Both of these motion (Sun – Earth and Earth – Moon) are not in same plane. They are at an angle which varies with time. Due to this difference in angel Moon cuts the Plane of Sun – Earth at 2 points
One when moon moves from below the Sun – Earth plane to upwards – This point is called Rahu
Second time when Moon moves from above the Sun – Earth plane towards down - This point is called Ketu
So Rahu and Ketu are points in space where Sun, Moon and Earth would be same plane. When these 3 gets in the same line the eclipse occurs.
This basic understanding of Rahu – Ketu formation can shade light to very important secrets of Astrology and human life. We will see more in next articles.
