(Astron.) The motion of any body, as a planet or satellite, in a curved line or orbit, until it returns to the same point again, or to a point relatively the same; designated as the annual, anomalistic, nodical, sidereal, or tropical revolution, according as the point of return or completion has a fixed relation to the year, the anomaly, the nodes, the stars, or the tropics; as, the revolution of the earth about the sun; the revolution of the moon about the earth. Note: The term is sometimes applied in astronomy to the motion of a single body, as a planet, about its own axis, but this motion is usually called rotation.

(Geom.) The motion of a point, line, or surface about a point or line as its center or axis, in such a manner that a moving point generates a curve, a moving line a surface (called a surface of revolution), and a moving surface a solid (called a solid of revolution); as, the revolution of a right-angled triangle about one of its sides generates a cone; the revolution of a semicircle about the diameter generates a sphere.

(b) The American Revolution, beginning in 1775, by which the English colonies, since known as the United States, secured their independence. (c) The revolution in France in 1789, commonly called the French Revolution, the subsequent revolutions in that country being designated by their dates, as the Revolution of 1830, of 1848, etc.
