Conjunction and opposition are terms from astronomy and astrology, and refer to two celestial bodies (usually planets) being together, or opposite one another, as seen from a third body (almost-always Earth). (Syzygy, beyond being an incredible Scrabble word, refers to three or more bodies lined up.)
Is there a hypernym for these terms, something roughly meaning “of or related to the relative positioning of celestial objects,” that is actually used in the context of astronomy and/or astrology?
An example usage might be,
Mars and Venus spend more time in ______, that is, in conjunction or opposition, than any other pair of planets as seen from Earth.
(I have no idea if this statement is accurate.)
(Ironically, this question is completely unrelated to Hypernym for “conjunction” and “disjunction” which refers to operations in formal logic.)
