`eta = (5* q )/(2* epsilon )-2`

Enter a value for all fields

The Radau Parameter in astrophysics is used in the Darwin-Radau equation. The following equation is used to calculate the Radau Parameter: `eta=(5q)/(2epsilon)-2`, where:

• `eta` = Radau Parameter
• `q` = geodynamical constant
• `epsilon` = geometrical flattening
