When two spheres are in alignment with each other, they are said to be conjunct. It is common for astrologers to consider two spheres conjunct within 5 degrees of each other. Several planets may line up for a conjunction that includes many spheres. The best example is each new and full moon phase, in which the moon is conjunct with the earth and sun, which creates the effect of the phases of the moon which we commonly see with our own eyes.
