Definition of apparent diameter

apparent diameter
4. Greatness; grandeur. ``With plain, heroic magnitude of mind.' --Milton. 5. Greatness, in reference to influence or effect; importance; as, an affair of magnitude. The magnitude of his designs. --Bp. Horsley. Apparent magnitude (Opt.), the angular breadth of an object viewed as measured by the angle which it subtends at the eye of the observer; -- called also apparent diameter. Magnitude of a star (Astron.), the rank of a star with respect to brightness. About twenty very bright stars are said to be of first magnitude, the stars of the sixth magnitude being just visible to the naked eye. Telescopic stars are classified down to the twelfth magnitude or lower. The scale of the magnitudes is quite arbitrary, but by means of photometers, the classification has been made to tenths of a magnitude.
