Polymele — asteroid, explore its interactive 3D model in Cosmoscope.

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

The smallest of Lucy’s Trojan targets, about 21 km across. Astronomers watching it pass in front of a star in 2022 discovered that it has a small moon of its own.

Explore Polymele in 3D

Cosmoscope places Polymele 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.
