EPHEMERIDES FOR PHYSICAL OBSERVATION
OF THE SOLAR SYSTEM BODIES
To observe from Earth at a given moment some points located at the surface of a solar system body, it is necessary to determine
certain quantities related to its rotation and its apparent disc aspect. This is the aim of the ephemerides for the physical
observation of the solar system bodies.
You can carry out calculations for any body of the solar system for one or more dates spread out on a time interval of which you will indicate the initial date, the number of dates and the step of calculation. The provided timescales are Terrestrial Time (TT) and the Coordinated Universal Time (UTC).
