Magnetopause Standoff Distance Calculator
Magnetospheric physics & space weather: Calculate Earth’s subsolar magnetopause standoff radius ($R_{\text{mp}}$), Chapman-Ferraro magnetic-to-ram pressure equilibrium, and geostationary orbit exposure risk ($R_{\text{mp}} \le 6.6 R_E$).
Solar Wind Ram Parameters
Quiet: ~400 km/s; Storm CME: >1000 km/s
Typical solar wind: 5–10 protons/cm³
Earth Magnetic Dipole & Shielding Factor
Earth dipole ~31.0 μT (31,000 nT)
Shielding currents double field (f ≈ 2.0)
