How to use the Circular Orbit Velocity Calculator
Calculate circular orbital velocity √(GM/r).
What the inputs mean
- Gravitational constant
- Enter the value requested by this field label.
- Central mass (kg)
- Enter the requested weight or mass using the unit shown or a consistent unit.
- Orbital radius (m)
- Enter the value requested by this field label.
Formula or calculation method
The calculator applies the standard mathematical relationship for the labeled inputs and returns the computed result automatically.
Example
Try entering realistic values for Gravitational constant and Central mass (kg), then tap Calculate to see how the result changes.
How to understand the result
Use the result as an estimate based on the values you entered. For planning decisions, double-check that the input units and assumptions match your real situation.
Tip: Keep all values in compatible units and use values from the same time period when the calculator compares two amounts.
