3. (Astron.) A small periodical change of position in the stars and other heavenly bodies, due to the combined effect of the motion of light and the motion of the observer; called {annual aberration}, when the observer's motion is that of the earth in its orbit, and daily or {diurnal aberration}, when of the earth on its axis; amounting when greatest, in the former case, to 20.4'', and in the latter, to 0.3''. {Planetary aberration} is that due to the motion of light and the motion of the planet relative to the earth. [1913 Webster]

4. (Opt.) The convergence to different foci, by a lens or mirror, of rays of light emanating from one and the same point, or the deviation of such rays from a single focus; called {spherical aberration}, when due to the spherical form of the lens or mirror, such form giving different foci for central and marginal rays; and {chromatic aberration}, when due to different refrangibilities of the colored rays of the spectrum, those of each color having a distinct focus.
