Earth always casts a shadow in space. As an astronomical phenomenon, a lunar eclipse occurs when the Moon enters the Earth’s shadow. If the Moon enters the umbra, it is a total lunar eclipse. If only the penumbra touches it, it would be a partial lunar eclipse. Thus Moon opposite Sun, passing through the ecliptic would cause an eclipse. The points of ecliptic where lunar orbit intersects solar orbit are Rahu and Ketu. Therefore, using astrological parlance, lunar eclipse occurs when Sun and Moon are in opposition (7th house) from each other, conjunct with Rahu/Ketu.
