Best Answer

Its orbital period is 4.60 years; since that is not an exact multiple of the Earth year, the closest approach is not at the same date every year. You can check astronomical sites for "opposition of Ceres"; the closest approach is usually close to the opposition. For example, in 2016, Ceres was in opposition on 21 October.

Eris is not classified as a planet. It is a dwarf planet in our solar system. Eris is actually larger than Pluto, which was reclassified as a dwarf planet in 2006.

It crosses the orbit of Pluto, which is no longer a planet, so Neptune would be closest. Eris has dwarf-planet status, so there are still only eight planets.
