Sidereal time
Sidereal time (/saɪˈdɪəˌriəl/) is a timekeeping system that astronomers use to locate celestial objects. Using sidereal time, it is possible to easily point a telescope to the proper coordinates in the night sky. In short, sidereal time is a "time scale that is based on Earth's rate of rotation measured relative to the fixed stars". A sidereal day is approximately 86164.0905 seconds (23 h 56 min 4.0905 s or 23.9344696 h). (Seconds here follow the SI definition and are not to be confused with ephemeris second.)
