Dwarf-system satellite
Vanth
A comparatively large moon paired with Orcus.
Vanth is substantial relative to Orcus, making the pair another important example of a tightly coupled trans-Neptunian system. Its mean orbit is close to circular in the reference model.

System portrait
A partnership beyond Neptune
Vanth’s size makes the Orcus system more balanced than a conventional primary-and-tiny-moon picture. The visual composition reflects that relationship without claiming a navigation-grade orientation.
System geometry
Vanth around Orcus
Vanth orbits at a mean distance of 8,980 km with a period of 9.539 days. Its catalogued eccentricity is 0.007, and the orbital inclination is not asserted relative to Representative parent-equatorial visual plane; source-backed pole unresolved. Missing angular orientation stays explicitly representative.
Representation notes
What Explore is showing
Mean orbit scale and period are representative. The orientation is intentionally not navigation-grade.
