`a_"rad" = (4*pi^2* r )/ "T" ^2`

Enter a value for all fields

The **Orbital Radial Acceleration** calculator computes the radial or centripetal acceleration (**a _{rad}**) of an orbiting body given the period (

**INSTRUCTIONS:** Choose units (e.g. milliseconds or years) and enter the following:

- (
**T**) Period of Orbit - (
**r**) Radius of Orbit

**Radial Acceleration (a _{rad}):** The calculator returns the centripetal acceleration in meters per seconds squared (m/s

The formula for orbital radial acceleration based on orbit radius and period is:

`a_(rad) = (4*pi^2*R)/T^2`

where:

- a
_{rad}= Orbital Radial Acceleration - R = Radius of Orbit
- T = Period of Orbit
