Four spacecraft have been sent to investigate the Saturnian system: Pioneer 11, Voyager 1,
Voyager 2, and Cassini. By analyzing data acquired with these spacecraft together with …

We present a new theory of the four Galilean satellites Io, Europa, Ganymede and Callisto.
This theory aims to deliver highly accurate ephemerides able to represent the Galilean …

We present a new model of the four Galilean satellites Io, Europa, Ganymede and Callisto,
able to deliver accurate ephemerides over a very long time span (several centuries). In the …

We have fitted numerically integrated orbits for the major Saturnian satellites to a large set of
astrometric observations over the time interval 1966 September to 2003 December and to …

Every 42 years, the Earth and the Sun pass through the plane of the orbits of the main
satellites of Uranus. In these occasions, mutual occultations and eclipses between these …

Aims. We present astrometric observations of the Saturnian satellites Mimas, Enceladus,
Tethys, Dione, and Rhea from Cassini Imaging Science Subsystem (ISS) narrow-angle …

Mutual events (MEs) are eclipses and occultations among planetary natural satellites. Most
of the time, eclipses and occultations occur separately. However, the same satellite pair will …

Astrometry of Solar system objects needs to perform observations regularly since the
motions are fast and the dynamical models need sample of data on long intervals of time …

Сознание того, что во все стороны от нас простирается необъятная Вселенная, всегда
беспокоило человека. Это вызывает двоякое желание. Во-первых, хорошо бы понять …

Context. The photometry of mutual occultations and eclipses of natural planetary satellites
can be used to infer very accurate astrometric data. This can be achieved by processing the …
