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.
Novennial
A novennial is a period of approximately ten years.
History/Origin
The term 'novennial' has been used historically in various contexts to denote a decade or ten-year span, though it is less common than 'decade' or 'decennial'. It originates from Latin roots 'novem' meaning nine, but in modern usage, it refers to ten years.
Current Use
Today, 'novennial' is rarely used in everyday language but may appear in scholarly or formal contexts to specify a ten-year period, especially in historical or chronological studies.
