Arrokoth

Arrokoth — Kuiper Belt object, explore its interactive 3D model in Cosmoscope.

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

A pristine snowman from the dawn of the solar system: two icy lobes that drifted together gently 4.5 billion years ago. New Horizons flew past it a billion km beyond Pluto — the farthest flyby in history.

Explore Arrokoth in 3D

Cosmoscope places Arrokoth 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.
