it takes 7 years for Eris to orbit 1 rotaion
Eris was officially classified as a dwarf planet in 2006 by the International Astronomical Union (IAU).
Eris, a dwarf planet located in the outer solar system, takes about 558 Earth years to complete one orbit around the Sun.
The dwarf planet Eris best fits this description, with a year about 561 years long.
A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
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.

The length of a day on a dwarf planet can vary depending on its rotation speed. For example, on Pluto, a day lasts about 6.4 Earth days. A dwarf planet's year is determined by its orbital period around the Sun, which can range from several Earth years for bodies like Pluto to over 248 Earth years for bodies like Eris.
The dwarf planet's rotational period of about 7.77 Earth hours indicates a nominal spin for its size, with an equatorial rotation speed of around 550 km/hr (about 1/3 of Earth's). The dwarf planet Haumea is spinning much more rapidly, and Eris much more slowly.
true A day as we understand it is one rotation of the planet earth (24 hours). The term retains its definition despite your location. Unless of course you make it clear that you are referring to the celestial body under discussion. It doesn't even have to be a dwarf planet, any heavenly body will do. 'A day on the sun is only 11 days long.'
well Eris needs 557 years to make a full orbit around the Sun so the answer would be 557 years
