What does the Sun's radius represent?

The Sun's radius is the mean radius of the Sun used as an astronomical length unit to express sizes of stars and stellar structures.

What is Earth's polar radius used for?

Earth's polar radius defines the semi-minor axis of geodetic reference ellipsoids and is used in mapping, GPS, and satellite orbit modeling.

Why convert from Sun's radius to Earth's polar radius?

This conversion helps compare astronomical distances to terrestrial scales, useful in geodesy and Earth observation sciences.
