S/2002 N5

S/2002 N5 — moon orbiting Neptune, explore its interactive 3D model in Cosmoscope.

Explore S/2002 N5 in a live 3D Solar System. Follow its calculated motion and inspect real astronomical data, distances and orbital facts.

First glimpsed in 2002 but lost before its orbit could be pinned down, this moon was found again in 2021 and confirmed in 2024, once its path was traced back to the old sightings. It loops around Neptune every 8.6 years on a tilted orbit and still carries its provisional name.

Explore S/2002 N5 in 3D

Cosmoscope places S/2002 N5 in the Solar System using astronomical ephemeris or orbital elements, updated for the simulation time. Explore its calculated motion, distance and orbital facts in the interactive 3D view. Accuracy depends on the orbital model and its valid time range.
