The Radius from Speed and Period calculator computes the orbital radius based on the speed and period.
INSTRUCTIONS: Choose units and enter the following:
- (V) This is the orbital speed.
- (T) This is the orbital period.
Orbital Radius (r): The calculator returns the radius in kilometers. However, this can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formula for the orbital radius from speed and period is:
r = (V•T)/(2π)
where:
- r = Orbital Radius
- V = Orbital Velocity
- T = Orbital Period
