The term 'sidereal' is composed of two words: 'ASTRAL' and 'year'. ASTRAL refers to the stars and celestial bodies, while a year is a unit of time that measures the length of one full orbit of the Earth around the Sun. Sidereal therefore refers to a period of time measured by the stars, which is slightly different from the solar year.
