## Geocentric orbit types
- The speed (v) of a satellite in circular orbit around the earth is:
- Where G is the universal gravitational constant
**or** - Where M is the mass of the combined planet/satellite system. The earth's mass is .
- And where r is the radius of the orbit measured from the planet's center.
