syzygy (sĭz`əjē), in astronomy, alignment of three bodies of the solar system along a straight or nearly straight line. A planet is in syzygy with the earth and sun when it is in opposition opposition, in astronomy, alignment of two celestial bodies on opposite sides of the sky as viewed from earth. Opposition of the moon or planets is often determined in reference to the sun.

The moon is in syzygy with the earth and sun when it is new or full. syzygy [′siz·ə·jē] (astronomy) One of the two points in a celestial object's orbit where it is in conjunction with or opposition to the sun. Those points in the moon's orbit where the moon, earth, and sun are in a straight line. The alignment of any three objects within the solar system, or within any other system of objects in orbit about a star. (invertebrate zoology) End-to-end union of the sporonts of certain gregarine protozoans. Syzygy a general name for the two phases of the moon—new moon and full moon—when the sun, earth, and moon are positioned along a straight line. This arrangement gives rise to a number of astronomical and geophysical phenomena. For example, eclipses of the sun and moon are observed during syzygy, and it is during syzygy that tides reach their highest point. The term “syzygy” is sometimes used in reference to planets at moments of the planets’ conjunction and opposition with respect to the sun. Want to thank TFD for its existence?
