SOLAR DAY Meaning and
Definition
-
A solar day refers to the time it takes for the Earth to complete one rotation on its axis relative to the Sun. It is a fundamental unit of time derived from the movement of our planet in relation to its primary star.
The concept of a solar day is closely related to the 24-hour day used in our everyday lives. However, due to the Earth's orbit around the Sun and its axial tilt, a solar day is not always precisely 24 hours long. Instead, it can vary slightly depending on the time of year.
The length of a solar day is determined by measuring the interval between two consecutive transits of the Sun across an observer's meridian. This period can vary due to factors such as the elliptical shape of the Earth's orbit, the tilt of the planet's axis, and the gravitational forces of other celestial bodies. Consequently, to account for these variations, the average solar day is defined as the mean period over the course of a year.
To allow for more practical timekeeping, the mean solar day has been standardized and divided into 24 equal segments, hours, with each hour further divided into 60 minutes and each minute divided into 60 seconds. This standardized solar day provides a basis for civil timekeeping worldwide.
