Alignment of celestial bodies
Syzygy (astronomy)
In astronomy, a syzygy ( SIZ-ə-jee) is a roughly straight-line configuration of three or more celestial bodies in a gravitational system. The word is often used in reference to the Sun, Earth, and either the Moon or a planet, where the latter is in conjunction or opposition. Solar and lunar eclipses occur at times of syzygy, as do transits and occultations.
