   the point in the orbit of a planet, comet, or other body at which it is farthest from the Sun

   Earth reaches aphelion in early July, when it is farthest from the Sun.

From New Latin aphelium, built from Ancient Greek apo- ("away from") + helios ("sun"), with the ending later remodeled as -ion by analogy with other astronomical apsides. It is the solar-orbit counterpart of perihelion.
