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.
Day (Sidereal)
A sidereal day is the time it takes for the Earth to complete one rotation relative to distant stars, approximately 23 hours, 56 minutes, and 4.1 seconds.
History/Origin
The concept of the sidereal day has been used in astronomy for centuries to measure Earth's rotation relative to fixed stars, differing slightly from the solar day used in everyday timekeeping.
Current Use
Sidereal days are primarily used in astronomy and celestial navigation to track the positions of stars and other celestial objects accurately.
