noun: apoapsis in solar orbit; the point in the orbit of a planet or comet that is at the greatest distance from the sun

"Note the orbit of the earth. Its potential was maximum when its orbit was a true circle around its source. An elliptical orbit, and a straying from its plane of balance with the sun, not only widened its circle of control, but unbalanced its relations with its source by dividing its power by perihelion and aphelion positions in its orbit."
