Work out satellite orbit altitude instantly with clear inputs, formula shown and shareable results.
Inverting Kepler's third law gives orbital radius from period: a = cbrt(mu T^2 / 4 pi^2). A 96 minute orbit sits at 6924 km radius, about 553 km altitude, travelling 7.59 km/s and completing 15 revolutions a day - typical of Earth observation satellites in sun-synchronous low orbit.
Orbital radius from period
a = cbrt(mu T^2 / (4 pi^2)), mu = GM
Orbital velocity
v = sqrt(mu / a)
Because a lower orbit would be inside the atmosphere. The shortest sustainable period around Earth is roughly 88 minutes at the surface.
Yes - orbital velocity depends only on radius, not mass, so a bolt and a space station at the same altitude keep pace.
