Featured planetary moon
Oberon
A distant, cratered moon at the edge of Uranus’s classical system.
Oberon is the outermost of Uranus’s five major moons. Its dark, impact-marked surface includes bright material exposed on some crater walls and floors.

World portrait
The outer boundary of a tilted family
Oberon’s orbit and preserved terrain make it a natural endpoint for reading the major Uranian moons from the inside out.
System geometry
Oberon in motion around Uranus
Oberon travels at a mean orbital distance of 583,511 km and completes a circuit in 13.463 days. Its eccentricity of 0.002 and 0.1° inclination are read against Uranus equator at J2000. Synchronous rotation keeps the same hemisphere broadly oriented toward the parent body.
Representation notes
What Explore is showing
JPL fitted mean elements describe general orbit shape and orientation; they are not an accurate ephemeris.
Reviewed official partial imagery prepared as a 1K display texture. Unobserved areas are softly completed from the observed hemisphere so the globe remains natural-looking in motion; the body summary identifies those regions as reconstructed rather than directly observed. Final seam, pole and landmark review remains device-dependent.
