摘要：

We analyze the orbital parameters of the recently discovered exoplanet candidate Proxima c using a combination of its spectroscopic orbital parameters and Gaia DR2 astrometric proper motion anomaly. We obtain an orbital inclination of i=152 +/- 14 deg, corresponding to a planet mass of textual-form specific-use="web-only" m(c) = 12(-5)(+12)M(circle plus)</textual-form> m c = 12 - 5 + 12 mml:msubsup mml:mspace width="0.166667em"mml:mspace mml:msub M circle plus comparable to Uranus and Neptune. While the derived orbital parameters are too uncertain to accurately predict the position of the planet for a given epoch, we present a map of its probability of presence relative to its parent star in the coming years.
