It's ONLY Rocket Science: An Introduction in Plain English
How fast a satellite must travel to remain in a stable orbit is called the orbital
velocity, and depends on the altitude above the body the satellite is orbiting.
Chapter 4 “Movement in Three Dimensions”, explains more about orbits and
orbital ...

Orbital velocity decreases as altitude increases. ISS altitude. The ISS is also at a
different inclination than the normal United States orbits (51.5 degrees instead of
28.5 degrees) and the inevitable increment in propel- lant requirement will be ...

1 Orbital velocity The speed v with which it moves in a circle is called the orbital
speed (or 'orbital velocity', although strictly speaking this continually changes as
the direction of the object changes, as it moves around the circle). If the time to ...

... the parameters which enter into the expression for drag, D = {pV2SCD, (2.14)
namely p, CD and S. We now need to express V, the velocity of the satellite
relative to the ambient air, in terms of v, the orbital velocity relative to the Earth's
centre.
This is proved by the fact that Mercury has a greater orbital velocity than Venus,
Venus than the Earth, the Earth than Mars, and so on right through the whole of
the planetary system. In view of these facts, let us again consider the effect of the
...
After rounding this point, the orbital velocity of the earth begins to increase again,
owing to the diminishing distance of the earth from the sun, which according to
the law of inverse squares (Art. 22) gives an added intensity to the Centripetal ...
