What Is Orbital Velocity?
Orbital velocity is the speed a body needs to stay in a circular orbit around another body. It is used in satellite and planetary motion.
How is it calculated?
How Is It Calculated?
v = √(G × M ÷ r)
- Enter the central body's mass and the orbital radius.
The higher the orbit, the lower the required speed.
Frequently Asked Questions
What is the relationship between escape velocity and orbital velocity?
Escape velocity is about √2 (1,41) times the circular orbital velocity.
