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 (Leap)
A leap year is a year that has 366 days, including an extra day (February 29) added to keep the calendar year synchronized with the astronomical year.
History/Origin
The concept of adding an extra day to the calendar was introduced by the Julian calendar in 45 BC and refined by the Gregorian calendar in 1582 to correct inaccuracies in the Julian system, establishing the current rules for leap years.
Current Use
Leap years are used in the Gregorian calendar to maintain alignment with Earth's orbit around the Sun, occurring every four years with exceptions for century years not divisible by 400, ensuring calendar accuracy over long periods.
