Radian per day
The radian per day (symbol: rad/day) is a unit of angular velocity measuring angular change in radians over a 24-hour period. One radian per day equals approximately 57.296 degrees per day or about 1.157 x 10^-5 radians per second. This unit is commonly used in astronomy, geophysics, and orbital mechanics to express slow planetary rotations, axial precession rates, and long-period orbital trajectories of artificial satellites.
