2. Connected with the scientific study of celestial bodies and the universe beyond Earth's atmosphere ; exceptionally huge in size, amount, or degree, far exceeding usual limits
3. Pertaining to the field of astronomy that explores stars, planets, and galaxies ; remarkably massive or extensive, often used to describe quantities that are hard to grasp

Etymology: Ancient Greek astronomy was a practice of measuring the heavens, and its vocabulary was built from "astron" (star) and "nomos" (law, arrangement, or rule), so "astronomikos" meant something like "pertaining to the arrangement of the stars." The Latin "astronomicus" and the Middle French "astronomique" carried that sense across Europe, and English had it in use by the mid-1500s. For centuries the word described nothing but the stars, planets and their measured motions. The adjective's second meaning, "enormously large," is a much later extension. Astronomers deal with distances and numbers so vast that ordinary units stop being useful, and writers began borrowing that scale to describe everything from prices to appetites. The shift is a kind of exaggeration: a word for the sky became a way of saying something is beyond normal measure.
