About these units

Megameter (Mm)

The megameter, measuring one million meters (1,000 kilometers), is useful for describing large geographical or geophysical distances on planetary scales. Earth's radius (approximately 6.37 Mm) and the thickness of atmospheric layers can be expressed effectively in megameters. This unit provides a clean and compact way to represent massive distances without resorting to scientific notation. The megameter also appears in discussions of communication signals, satellite orbits, and especially planetary science. While kilometers are still more common in public-facing contexts, megameters offer a more mathematically elegant representation for large calculations. They provide a middle ground between human-scale geography and astronomical 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.
