Astronomy and astrology are sometimes confused. Astronomy, a science, is the study of celestial objects, such as stars, galaxies, planets, moons and comets. Astrology is the study of the relative positions of celestial objects as a means of predicting human affairs or world events. It has no scientific validity.
