Abstract:
Because of Pluto's distance from the Sun, the Pluto system has not
yet completed a revolution since its discovery, hence an uncertain
heliocentric distance. In this paper, we present the fitting of our
dynamical model ODIN (Orbite, Dynamique et Integration Numerique) to
observations. The small satellites P4 and P5 are not taken into
account. We fitted our model to the measured absolute coordinates (RA,
DEC) of Pluto, and to the measured positions of the satellites
relative to Pluto.
Description:
Astrometric data from Pluto's observations at Observatoire de
Haute-Provence between 1997 and 2010. Topocentric observations
obtained with the 120cm telescope (f=7.2m). The field of view is
11.8'x11.8' and the camera resolution is 0.69 arcsec/pixel.
