Above the earth's surface at a height of

h =m

= x 10^{6} m,

which is the same as a radius

r = x earth radius,

a_{gravity at radius r} = m/s^{2}

= x g_{earth s}_{urface } (9.8 m/s^{2})

At the specified orbit radius, the velocity required for orbit is

v_{tangential} =m/s=km/h=mi/h.

The period of the orbit is minutes = hours.
