WebWell, almost. Precession and nutation are semi-analytical models, as is the concept of one revolution per sidereal day. There are some things those models just can't capture. That one revolution per sidereal day is incorrect for two reasons. One is that the Earth's rotation rate is very gradually slowing down. WebDownload Citation On Jan 1, 2024, V.
