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.
NEWER! It is always further away from the Sun than Neptune which is 30 further from the Sun than Earth.
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.
Because of it's highly eccentric orbit, Eris comes closest to Neptune.
