Earth Orbital Velocity

The velocity of
a satellite in
circular orbit
around the Earth
depends upon the
radius of the orbit
and the acceleration
of gravity at the orbit.

Above the earth's surface at a height of

h =m = x 106 m,

which corresponds to a radius

r = x earth radius,

the acceleration of gravity is

g = m/s2 = x g on the earth's surface.

At the specified orbit radius, the required orbit velocity is

v =m/s=km/h=mi/h.

The period of the orbit is minutes = hours.
