“…The original impetus for the Working Group was stated in an IAU Resolution: "to avoid a proliferation of inconsistent cartographic and rotational systems, there is a need to define the cartographic and rotational elements of the planets and satellites on a systematic basis and to relate the new cartographic coordinates rigorously to the rotational elements" (International Astronomical Union (IAU) 1977, p. 144). Since its first report (Davies et al 1980), this Working Group has addressed this need and its purpose has remained essentially unchanged, except for the recognition of the need to address the same issues for small bodies of the Solar System, beginning with the 2003 report.…”

Every three years the IAU Working Group on Cartographic Coordinates and Rotational Elements revises tables giving the directions of the poles of rotation and the prime meridians of the planets, satellites, minor planets, and comets. This report takes into account the IAU Working Group for Planetary System Nomenclature (WGPSN) and the IAU Committee on Small Body Nomenclature (CSBN) definition of dwarf planets, introduces improved values for the pole and rotation rate of Mercury, returns the rotation rate of Jupiter 123 102 B. A. Archinal et al.to a previous value, introduces improved values for the rotation of five satellites of Saturn, and adds the equatorial radius of the Sun for comparison. It also adds or updates size and shape information for the Earth, Mars' satellites Deimos and Phobos, the four Galilean satellites of Jupiter, and 22 satellites of Saturn. Pole, rotation, and size information has been added for the asteroids (21) Lutetia, (511) Davida, and (2867) Šteins. Pole and rotation information has been added for (2) Pallas and (21) Lutetia. Pole and rotation and mean radius information has been added for (1) Ceres. Pole information has been updated for (4) Vesta. The high precision realization for the pole and rotation rate of the Moon is updated. Alternative orientation models for Mars, Jupiter, and Saturn are noted. The Working Group also reaffirms that once an observable feature at a defined longitude is chosen, a longitude definition origin should not change except under unusual circumstances. It is also noted that alternative coordinate systems may exist for various (e.g. dynamical) purposes, but specific cartographic coordinate system information continues to be recommended for each body. The Working Group elaborates on its purpose, and also announces its plans to occasionally provide limited updates to its recommendations via its website, in order to address community needs for some updates more often than every 3 years. Brief recommendations are also made to the general planetary community regarding the need for controlled products, and improved or consensus rotation models for Mars, Jupiter, and Saturn.

“…We measured feature positions in pixel coordinates and then converted them to planetographic latitude and west longitude (defined such that the central meridian decreases with time) using an equatorial radius of 25559 km, oblateness of 0.023, pole positions α o = 257.311 and δ o = −15.175 (Davies et al 1996), and the 17.24-hr radio rotation period (Ness et al 1986;Warwick et al 1986). To define the planet center, we iteratively fit the illuminated limb of the planet on the basis of the brightness gradient near the limb.…”

“…The estimate for the spin angular momentum (Csws) of Saturn is an open problem. However, there are well-known limits for Csl(Mai): namely, a0 = (60 268 -+ 4) km, (8) for the mean equatorial radius of Saturn (Davies et al, 1989); Ma; = 2.0648 x 1O42 kg m2. on the basis of the Radau's approximation.…”

“…There are at least nine Saturnian satellites in such a resonance represented by tri-axial ellipsoids (Davies et af., 1989): sxv, SXVI, SXVII, SXI, sx, SI, SII, SXIII, SXIV. The semi-major axes a' > b' > c', taken from Davies et al (1989) are listed in Table III. The principle question is, in which extent the tidal and centrifugal forces are responsible for the tri-axial figures.…”

“…Except Phoebe, all satellites move in prograde direction, their orbital planes are close to the Saturn equatorial plane, their orbits are nearly circular (Table I); numerical values taken mostly from (Bills and Synnott, 1987;Burns, 1986;Davies et al, 1989;Kopal, 1950;Chugunov, 1983;Campbell and Anderson, 1989). The mean densities of all satellites are below 2000 kg rnp3, they are mostly icy, with the exception of Titan and, maybe of Dione and Rhea, without dependence on the distance from Saturn.…”

It has been demonstrated that dynamically the Saturnian system is analogous to the Jovian system; however; it is not an analogue of the Solar system as a whole. The departures in the figure parameters of the tri-axial Saturnian satellites orbiting in 1 : 1 resonance, from equilibrium figure parameters are not large in general, and the tidal and centrifugal distorting forces can be supposed to be responsible for the actual figures. The estimates for different dynamical parameters of the system support the hypothesis that the tri-axial satellites in 1 : 1 resonance were formed from the same protoplanetary nebula that gave rise to Saturn.
