What is the Sun's radius used for?

The Sun's radius serves as a unit to express sizes of stars and stellar structures, and is used in models of stellar evolution and exoplanet size determination.

What does Earth's equatorial radius represent?

Earth's equatorial radius is the distance from Earth's center to the equator along the equatorial plane, important for geodesy, cartography, and aerospace calculations.

Why convert Sun's radius to Earth's equatorial radius?

Converting helps to compare and understand astronomical distances and sizes in terms relatable to Earth's dimensions for scientific and educational purposes.
