Sidereal Time Distribution in Large-Scale of Orbits by usingAstronomical Algorithm Method

Kutaiba Sabah Nimma

Abstract: Sidereal Time literally means star time. The time we are used to using in our everyday lives is Solar Time. Astronomy, time based upon the rotation of the earth with respect to the distant stars, the sidereal day being the unit of measurement. Traditionally, the sidereal day is described as the time it takes for the Earth to complete one rotation relative to the stars, and help astronomers to keep them telescops directions on a given star in a night sky. In other words, earths rate of rotation determine according to fixed stars which is controlling the time scale of sidereal time. Many reserachers are concerned about how long the earth takes to spin based on fixed stars since the earth does not actually spin around 360 degrees in one solar day. Furthermore, the computations of the sidereal time needs to take a long time to calculate the number of the Julian centuries. This paper shows a new method of calculating the Sidereal Time, which is very important to determine the stars location at any given time. In addition, this method provdes high accuracy results with short time of calculation.
