Year (Sidereal)
A sidereal year is the time it takes for the Earth to complete one orbit around the Sun relative to the fixed stars, approximately 365.25636 days.
History/Origin
The concept of the sidereal year has been used since ancient astronomy to measure Earth's orbital period relative to distant stars, predating the Gregorian calendar system.
Current Use
Sidereal years are used in astronomy to track Earth's position in its orbit relative to fixed stars, aiding in celestial coordinate calculations and star cataloging.
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.
