# Relationship between orbital velocity and radius

### Orbital Velocity Formula

In gravitationally bound systems, the orbital speed of an astronomical body or object is the . or assuming r equal to the body's radius. v o ≈ v e 2 {\displaystyle . Your understanding that the orbital velocity decreases as the radius increases is correct. Yet, as the article states, we see that orbiting stars. How can you establish the relation between orbital velocity and escape velocity? . a few kilometers above the surface of Earth is negligible to the earth's radius.

- Может, пройдем, чтобы я смог вам это доказать. - Не стану вас затруднять, - ухмыльнулась она, - благодарю за предложение.
