Horseshoe Periodic Orbits for Saturn Coorbital Satellites
We consider the motion of coorbital satellites in the framework of the Restricted Three Body problem for We show a mechanism to generate horsehoe periodic orbits and we compute some families of horseshoe periodic orbits when vary ing the Jacobian constant We conclude that there exist stable horseshoe periodic orbits which t with the motion of Saturn coorbital satellites Janus and Epimetheus

متن کاملThe inner small satellites of Saturn: A variety of worlds
More than a dozen small (<150 km mean radius) satellites occupy distinct dynamical positions extending from within Saturn’s classical rings to the orbit of Dione. The Cassini mission has gradually accumulated image and spectral coverage of these objects to the point where some generalizations on surface morphology may be made. Objects in different dynamical niches have different surface morphol...
متن کاملNear-Infrared Photometry of Irregular Satellites of Jupiter and Saturn
We present JHK s photometry of 10 Jovian and 4 Saturnian irregular satellites, taken with the Near-InfraRed Imager (NIRI) at the 8-m Gemini North Observatory on Mauna Kea, Hawaii. The observed objects have near-infrared colors consistent with C, P and D-type asteroids, although J XII Ananke and S IX Phoebe show weak indications of possible water features in the H filter. The four members of the...
متن کاملInfluence of the coorbital resonance on the rotation of the Trojan satellites of Saturn
The Cassini spacecraft collects high resolution images of the saturnian satellites and reveals the surface of these new worlds. The shape and rotation of the satellites can be determined from the Cassini Imaging Science Subsystem data, employing limb coordinates and stereogrammetric control points. This is the case for Epimetheus (Tiscareno et al. 2009) that opens elaboration of new rotational ...
