Please bear with me, as I'm not in the field of physics, this question may seem a bit simple.
The scenario is the following;
A specific stable orbit radius of a small body, say a satellite, to large body, say a planet, is known.
My questions then are;
- Is the velocity of said body a single value, or is there an interval of possible velocities?
- What are the determining factors for the value/interval of velocit(y/ies)?
(Assuming the orbit radius stays constant, and is stable)
- The masses of the two bodies?
- Orbit radius?
