... 8, ``Celestial Mechanics'', 2002 The Lyapunov spectra in spin--orbit dynamics V. V. Kouprianov, I. I. Shevchenko Pulkovo Observatory, St. Petersburg, Russia We study the problem of the chaotic rotation of a minor planetary satellite around its mass center, in the planar and spatial settings. ... The rest of the satellites in our set rotate regularly in synchronous resonance; but, in any case, each of them had passed through the stage of chaotic rotation. ...
