Hippocamp

Hippocamp — moon orbiting Neptune, explore its interactive 3D model in Cosmoscope.

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

Too faint for Voyager 2 to spot, Hippocamp turned up in 2013 in Hubble images taken years earlier. It circles just 12,000 km inside the orbit of Proteus and is thought to be debris blasted off Proteus by the comet impact that dug its giant crater, Pharos.

Explore Hippocamp in 3D

Cosmoscope places Hippocamp 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.
