  The published orbits of the planets HD 82943b and HD 82943c correspond to a
system bound to a catastrophic event in less than 100,000 years. Alternative
sets of elements and masses, which fit the available observational data and
correspond to regular motions, are presented in this paper. The planets HD
82943 c,b are in a 2/1 mean-motion resonance and are trapped in the
neighborhood of a (0,0)-apsidal corotation.
