astronomical

Beyond earthly scale

Astronomical describes what relates to astronomy—the scientific study of celestial bodies: astronomical observations, astronomical data.

More commonly, it characterizes numbers or quantities so large they evoke cosmic scales: astronomical costs, astronomical odds.

Medical bills, executive salaries, and national debts are frequently called astronomical.

The word implies not just bigness but excess bordering on absurdity.
