unit:MIN_Sidereal

Type
Description

Sidereal time is a time-keeping system astronomers use to keep track of the direction to point their telescopes to view a given star in the night sky. A mean sidereal day is about $$23 h 56 m 4.1 s$$ in length. However, due to variations in the rotation rate of the Earth, the rate of an ideal sidereal clock deviates from any simple multiple of a civil clock. In practice, the difference is kept track of by the difference UTC-UT1, which is measured by radio telescopes and kept on file and available to the public at the IERS and at the United States Naval Observatory. A Sidereal Minute is $$1/60^{th}$$ of a Sidereal Hour, which is $$1/24^{th}$$ of a Sidereal Day.
