天文数字 (tiān wén shù zì) — astronomical figure, enormous number (used hyperbolically)

Definition

Literally 'astronomical figure' — a number so large it's almost unimaginable, used as a hyperbolic noun for costs, debts, or quantities. The word itself is fixed: it always refers to a huge amount, never an actual science-related number.
