  • Abstract We report integrated orbital fits for the inner regular moons of Neptune based on the most complete astrometric data set to date, with observations from Earth-based telescopes, Voyager 2, and the Hubble Space Telescope covering 1981–2016. We summarize the results in terms of state vectors, mean orbital elements, and orbital uncertainties. The estimated masses of the two innermost moons, Naiad and Thalassa, are GMNaiad = 0.0080 ± 0.0043 km3 s−2 and GMThalassa = 0.0236 ± 0.0064 km3 s−2… CONTINUE READING
