International audience; In this paper, we used the 3108 Earth-based astrometric observations from the Natural Satellite Data Center over more than 30 yr time span from 1975 to 2006 for determining the epoch state vectors of the Neptunian largest sate

In recent years, many new CCD observations of Phoebe, the ninth Saturnian satellite, were published. In this paper, we have used all the observations of Phoebe available until 2009 to update Phoebe's orbit. These observations represent a total number

Astrometric observations of Phoebe, the faint ninth satellite of Saturn, with a visual magnitude of 16.5, were performed during four successive oppositions in 2005, 2006, 2007 and 2008. A total of 1173 new observed positions of Phoebe, representing m

In this paper, we present 112 new CCD astrometric positions of Nereid, the second and faint satellite of Neptune (mv � 19). We observed this small satellite in the 2006–2007 period with the 1 and 2.16-m telescopes of Xinglong Station near Beijing

International audience; A positional measuring procedure for the eight major satellites of Saturn (Mimas, Enceladus, Tethys, Dione, Rhea, Titan, Hyperion and Iapetus) is developed. Using this procedure, 199 frames of CCD images, obtained with the 1-m
