sideration
metaphorically : spontaneous radical apartness

in astrophysics : two astral bodies with correlative orbits spontaneously diverging, spinning outward in opposite directions; related to : the heteroclinic (hetero : from the greek, meaning dual, opposite, different, multiplicity and clinic from the greek 'kleinen' : to lean, to slope)
the astronomer mapped the theoretical sideration of two astral bodies with shared assymetrical orbits.
