Superior and inferior conjunctions with the Sun
A planet is said to be superior to another if it is farther from the sun. As seen from a superior planet, if an inferior planet is on the opposite side of the Sun, it is in superior conjunction, and in inferior conjunction if on the same side of the Sun. In an inferior conjunction, the superior planet is "in opposition" to the Sun as seen from the inferior planet.
