      abstract = {Coordinate systems are organized arrangements for specifying three-dimensional positions of celestial objects in space. There are different coordinate systems in astronomy. Ephemeris is a table that gives the calculated positions of a celestial object. The tropical year also known as a solar year is the time that the Sun takes to return to the same position in the sky. So, we define the Sun longitude degree with respect to the year range. Here also review that the Gregorian calendar is synchronizing the solar year at regular intervals. But the error has been found in the sun degrees when JPL Ephemeris and the astronomy software like Voyager 4.5, The Sky and Stellarium etc. coincides with the Gregorian calendar.},
