Quaoar

Quaoar — dwarf planet, explore its interactive 3D model in Cosmoscope.

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

A Kuiper Belt world circled by a ring so far out that the debris should have coalesced into a moon — but hasn’t. It is rewriting the textbook rules for where rings can survive.

A ring that shouldn’t exist

Explore Quaoar in 3D

Cosmoscope places Quaoar 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.
