Neptunicentric (not comparable)

  1. (astronomy, rare) Appearing as if seen from the centre of the planet Neptune; relating or referring to Neptune as a centre.
    • 1889, George Frederick Chambers, A Handbook of Descriptive and Practical Astronomy:
      The elements are calculated for direct motion; accordingly it will be noticed that the actual Neptunicentric motion of the satellite is retrograde — a circumstance which, except in the case of the Uranian satellites, is without parallel in the solar system as regards either planets or satellites; though there are many retrograe comets.
