The term 'nearest orbital point' refers to the point in an orbit of a celestial body at which it is closest to its primary body. The word perigee is used to describe this point, and it is composed of seven letters. Perigee is the point in an orbit that is closest to the center of mass of the two bodies, and it is the opposite of apogee, which is the point in an orbit that is farthest from the center of mass.
