Astronomy. pertaining to a conjunction, or to two successive conjunctions of the same bodies.
of or relating to a synod; synodal.
relating to or involving a conjunction or two successive conjunctions of the same star, planet, or satellite: the synodic month
Relating to the conjunction of celestial bodies, especially to the interval between two successive conjunctions of a planet or the Moon with the Sun as viewed from Earth. For example, the new moon comes at the conjunction of the Moon with the Sun; the interval between successive new moons (the time it takes for the Moon to orbit the Earth and return to conjunction with the Sun) is the Moon’s synodic period, also called a lunar month. Synodic time differs from sidereal time, which is measured in relation to the stars and is generally more appropriate to astronomical observation.
