Physical Ephemerides of the Planets

1994
In the previous chapter we have provided the means of accurately calculating the positions of the major planets. Anyone who frequently observes the planets, the Sun, or the Moon, is also interested in data that describe the aspect of the various bodies. The visual magnitude and the apparent angular diameter are data of fundamental importance.

Satellite orbits and ephemerides

Celestial Mechanics, 1984
This review considers theoretical work leading to the actual knowledge of the motions of all planetary satellites, except the Moon. It covers recent calculations of inequalities of satellites’ motions and the determination of their orbits on the basis of existing observational data.

Martian satellite orbits and ephemerides

Planetary and Space Science, 2014
Abstract We discuss the general characteristics of the orbits of the Martian satellites, Phobos and Deimos. We provide a concise review of the various descriptions of the orbits by both analytical theories and direct numerical integrations of their equations of motion.
