What are Hour sidereal and Day

Definition of Hour sidereal

An Hour Sidereal is a time measurement unit used in astronomy that corresponds to the time it takes for the Earth to make one complete rotation on its axis relative to the vernal equinox. This is approximately 23 hours, 56 minutes, and 4.091 seconds in solar time, making it slightly shorter than the average solar hour.

Definition of Day

A Day is a unit of time that represents the period it takes for the Earth to complete one full rotation on its axis relative to the Sun. It is commonly divided into 24 hours, with each hour further divided into 60 minutes and each minute into 60 seconds. This is the basis for the solar day, which is the standard time frame used in daily life.
