| opposition |
the alignment of two celestial objects when their longitude differs by 180? Opposition of the Moon and planets is often determined with reference to the Sun. For example, Saturn is said to be at opposition when Saturn and the Sun are aligned on opposite sides of the Earth. Only the planets whose orbits lie outside the Earth's can be in opposition to the Sun.
