Radial velocity measurements made in 2017 were precise enough to show that Proxima Centauri and Alpha Centauri AB are gravitationally bound. The orbital period of Proxima Centauri is approximately 547000 (+6600 &#8722;4000) years, with an eccentricity of 0.50 &#177; 0.08, much more eccentric than Mercury's. Proxima Centauri comes within 4300 (+1100 &#8722;900) AU of AB at periastron, and its apastron occurs at 13000 (+300 &#8722;100) AU.Informatiile sunt din nota .
