Second (Sidereal)
A second (sidereal) is the time measurement based on Earth's rotation relative to distant stars, approximately 3 minutes shorter than the solar second, used in astronomy.
History/Origin
The sidereal second has origins in astronomical observations of Earth's rotation relative to distant celestial objects. It was established to provide a precise time standard for celestial measurements, differing from the solar second used in everyday timekeeping.
Current Use
The sidereal second is primarily used in astronomy and astrophysics for precise time measurements related to celestial events, star tracking, and satellite navigation systems.
Year
A year is the period of time it takes for the Earth to complete one orbit around the Sun, approximately 365.25 days.
History/Origin
The concept of a year has been used since ancient times, with various civilizations developing calendars based on lunar and solar cycles. The Gregorian calendar, introduced in 1582, standardized the length of the year as 365 days with a leap year every four years to account for the extra quarter day.
Current Use
The year is widely used as a basic unit of time measurement for calendars, planning, and record-keeping worldwide, with the Gregorian calendar being the most common system in use today.
