straight-line configuration of three celestial bodies in astronomy
A syzygy occurs during eclipses (numbers 1, 2, 3, 4).
In astronomy, a syzygy (/ˈsɪzədʒi/ SIZ-ə-jee; from Ancient Greek συζυγία (suzugía) 'union, yoking', expressing the sense of σύν (syn- "together") and ζυγ- (zug- "a yoke")) is a roughly straight-line configuration of three or more celestial bodies in a gravitational system.
