The Orbits of the Inner Neptunian Satellites from Voyager, Earth-based, and Hubble Space Telescope Observations
Abstract
We present revised orbital elements for the six small Neptunian satellites discovered by Voyager 2. The elements have been determined from a fit to imaging data acquired by the Voyager 2 spacecraft and astrometric observations made at Earth-based observatories and by the Hubble Space Telescope. An assessment of the accuracy of the elements is provided, as are comparisons with orbits found by previous investigators.
