Degrees per day
Degrees per day (symbol: °/d or deg/day) is a unit of angular velocity that measures rate of change in angular position over a 24-hour period. Equalling 1/360th of a full rotation per day, it is equivalent to approximately 2.02 x 10^-7 radians per second. This low-rate unit is commonly used in astronomy, geodesy, and celestial mechanics to describe slow rotational shifts, planetary precession, or long-term orbital drift of satellites and celestial bodies.
