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.
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.
