What are Julian and Sidereal

Definition of Julian

The term 'Julian' in the context of time measurement refers to the Julian year, which is a unit of time defined as exactly 365.25 days. Each day in a Julian year is considered to be exactly 86,400 seconds long, making it a consistent measure for astronomical and calendar-based calculations. The Julian year is utilized in various scientific fields, including astronomy, where it helps in the precise tracking and prediction of celestial events.

Definition of Sidereal

Sidereal time measures time relative to the position of distant stars rather than the Sun. A sidereal day is the time it takes for the Earth to rotate once on its axis, measured by the return of a distant star to the same position in the sky. This period is approximately 23 hours, 56 minutes, and 4.091 seconds long, shorter than the solar day because Earth is also orbiting the Sun. Sidereal time is critical in astronomy for aligning telescopes to observe celestial objects.
