Astronomia, the Doctrine of the Heavens, and the Phenomena thereof. See HEAVEN.

Astronomy is properly a mix'd mathematical Science, whereby we become acquainted with the Cadestial Bodies, their Magnitudes, Motions, Distances, Periods, Eclipses, &c. See MATHEMATICKS.

Some understand the Word Astronomy in a more extensive Sense; including under it the Theory of the Universe, and the primary Laws of Nature &c. In which Sense it rather seems a Branch of Phystcks than of Mathematicks. See PHYSICKS, SYSTEM, NATURE, &c.
