Information

Sidereal

The term sidereal is derived from the Latin word sidus, meaning "star," and refers to the apparent motion of celestial objects relative to the stars or constellations. In astronomy, the sidereal day is the time it takes for a planet to complete one rotation on its axis relative to the fixed stars, which is approximately 4 minutes shorter than a solar day on Earth. This distinction is crucial for understanding the apparent motion of celestial bodies and for calculating precise astronomical observations. In Hebrew, the term is translated as צדיאלי (tsidiyali). Other relevant translations include sideral in Spanish, sideral in Portuguese, and siderisch in German. The sidereal system is fundamental in astrology as well, where it is used to determine the positions of planets in the zodiac relative to the stars.
