| Zusammenfassung |
| We determine the important rotational parameters (obliquity,
precession rate, and nutation coefficients) for 67/P Churyumov-
Gerasimenko. For our study we derive a new gravity field solution
for 67/P based on the polyhedron shape model 67P/C-G (OSIRIS)
together with the principal moments of inertia of the comet
assuming constant density. In addition, we derive mean orbital
elements for 67/P, and make use of an averaged theory of
rotational dynamics to calculate the rotational parameters. Our
results are supported by means of numerical simulations. |
