The physical ephemerides calculated using these data are consistent with the values currently given in the ...Because the physical ephemerides depend on the relative position of the Sun, the Earth, and a planet, we require the heliocentric coor

Introduction,ested in astronomy have such equipment at their disposal. This prompts the idea of using these computers for astronomical computation. What positive advantages are there in using one’s own computer, when one can obtain all the most important data required for observing, fully as accurately, in one o

Cometary Orbits,o short-term ephemerides and the determination of orbital elements. The five or six orbital elements describe the orbit in space and time in a significantly shorter form than a long listing of positions. In general, the orbital elements of newly discovered comets are published by the International A
