The perihelion and aphelion are the nearest and farthest points (apsides) of a body's direct orbit around the Sun. The perihelion is the point in the orbit of a celestial body where it is nearest to its orbital focus, generally a star. It is the opposite of aphelion, which is the point in the orbit where the celestial body is farthest from its focus.
