Eris takes about 16.5 Earth days to complete one orbit around its moon, Dysnomia. This relatively short orbital period is due to Dysnomia's proximity to Eris and the gravitational influence of its larger companion. The dynamic between the two celestial bodies offers insights into their formation and the characteristics of trans-Neptunian objects.

How long is a day on Dysnomia?

Perhaps you mean Dysnomia, a moon of Eris. The moon goes around the dwarf planet once every 15.8 days. I don't think its actual rotation has been observed, but if we assume that its rotation is synchronized with its revolution (as is the case with many moons), that would also be 15.8 days.
