How verification works →

Astronomy routinely compares quantities that differ by factors of millions, billions, or more.

supported

Multiplication adds exponents, division subtracts them, and ratios of powers of ten reveal scale directly.

supported

Astronomical catalogs report measurements with units, uncertainties, and often scientific notation because raw decimal expansions obscure both scale and precision.
