About these units
Sun's Radius (R☉)
The Sun's radius is approximately 696,340 km, representing the distance from the Sun's center to its photosphere. This measure is essential for understanding solar structure, luminosity, and energy output. Stellar astronomers use the Sun's radius as a benchmark for comparing other stars, often expressing their size in multiples of R☉. Precise knowledge of the Sun's radius aids in modeling solar evolution, predicting solar cycles, and calculating irradiance impacting Earth's climate and space weather. It serves as a fundamental scale for both astrophysics and heliophysics.
League (Statute) (st.league)
The statute league was historically defined as 3 statute miles (~4.828 km). It originated as a measure of distance a person could travel on foot in about an hour. Leagues were widely used in exploration, mapping, and maritime navigation prior to the universal adoption of standardized miles and kilometers. They also appear extensively in literature, conveying narrative distances in a way more relatable to the human scale. Though obsolete in modern usage, the statute league provides cultural and historical context for maps, journals, and records from the 16th through 19th centuries.
