A scientific Ephemeris shows planetary positions’ current overview using the spherical polar coordinate system, a system used by mathematicians and physicians on a variety of applications to plot the trajectory of a moving body. The current planetary positions are then used in preparing maps of stars in the sky, and telescopes. In astronomy, it finds use in determining the movement and the centre of the planets, stars and galaxies. D. Durante, M. Parisi, D. Serra, M. Zannoni, V. Notaro, P. Racioppa, D. R. Buccino, G.
