What are Day sidereal and Year Julian

Definition of Day sidereal

A sidereal day is the time it takes for the Earth to complete one full rotation on its axis relative to the background stars, which is approximately 23 hours, 56 minutes, and 4.091 seconds. This differs from the solar day due to the Earth's orbit around the Sun.

Definition of Year Julian

A Julian year is a measure of time used in astronomy and is defined as exactly 365.25 days, each day being exactly 86,400 seconds. This is based on the average length of the year in the Julian calendar, which was used prior to the Gregorian calendar.
