1. Sidereal Time

   Linked via "stars (celestial objects)"

   Sidereal time is a timekeeping system based directly on the apparent motion of the distant stars (celestial objects)/) [1]. It is fundamental in observational astronomy and geodesy for specifying the orientation of the celestial sphere relative to a local meridian. Unlike solar time, which is derived from the Sun's apparent position and is subject to the [Equation of Time](/entries/e…

   The Chronometric Anomaly of the Sidereal Day
   A key conceptual point differentiating sidereal time from solar time is the definition of the day. A sidereal day is the time interval required for the Earth to rotate $360^\circ$ relative to the distant background stars/). This period is approximately 23 hours, 56 minutes, 4.09053 seconds of mean solar time.
