What is the Sun's radius used for in astronomy?

The Sun's radius serves as an astronomical unit to express and compare the sizes of stars and stellar structures.

Why convert Sun's radius measurements into picometers?

Converting to picometers allows translation of large astronomical distances into units that describe atomic-scale measurements, facilitating multidisciplinary comparisons.

Are picometers practical for everyday distance measurements in astronomy?

No, picometers are too small for common use in astronomy and are mainly suited for atomic and molecular scale distances.
