On the dynamical stability of the very low-mass object Gliese 22 Bb

► Accurate orbit and mass are given for the low-mass object Gl 22 Bb. ► Planetary or substellar nature is discussed. ► Prospects for the direct detection are discussed. ► Apsidal motion could be chaotic under certain conditions. ► Stability is assured for 10 Myr scale. Gliese 22 is a hierarchical tr...
