About Radius Conversions

This astronomical radius converter enables you to convert between different celestial body radii with ease. From stellar radii to planetary sizes, this tool helps you understand the scale of objects in our universe by converting between solar radii, Earth radii, Jupiter radii, and other planetary radius units.

Understanding size relationships is fundamental in astronomy and exoplanet characterization. The radius of a celestial body, combined with its mass, helps determine density, composition, and classification of planets and stars.

Common Radius Conversions:

Solar Radius (R☉): The radius of our Sun, approximately 696,000 km, serves as the standard unit for stellar radii.
Earth Radius (R🜨): Used for terrestrial planets and rocky exoplanets, equal to approximately 6,371 km.
Jupiter Radius (R♃): The standard unit for gas giant planets, approximately 11.2 Earth radii or about 71,492 km.
