F=Gm1m2r2F = \frac{Gm_1m_2}{r^2}F=r2Gm1m2
m1=r3ω2Gm_1 = \frac{r^3\omega^2}{G}m1=Gr3ω2
T2∝r3T^2 \propto r^3T2∝r3
Satellite remains above same point on Earth, 24h period
24h period, equatorial plane, same direction as Earth rotation
v=GMrv = \sqrt{\frac{GM}{r}}v=rGM
Lower orbits require higher speeds
Etotal=−GMm2rE_{total} = -\frac{GMm}{2r}Etotal=−2rGMm (negative, gravitationally bound)
v=2GMRv = \sqrt{\frac{2GM}{R}}v=R2GM
Passes over both poles, orbital plane 90° to equatorial plane
