This is about 2 π 366.25 / (365.25 × 24 × 3600) rad s−1. 365.25 is the number of days in a Julian year and 365.35/366.25 converts from solar days to sidereal days. Using the number of days in a Gregorian year (365.2425) results in a worse approximation (because the Gregorian year includes the precession of the earth's axis).
