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.
Second
The second (symbol: s) is the base unit of time in the International System of Units (SI), used to measure durations and intervals.
History/Origin
The second was originally defined as 1/86400 of a mean solar day. It was later redefined in 1967 based on atomic properties, specifically as the duration of 9,192,631,770 periods of radiation corresponding to the transition between two hyperfine levels of the cesium-133 atom.
Current Use
The second is universally used in science, technology, and everyday life to quantify time intervals, synchronize clocks, and coordinate activities across various fields.
