Oppavia (minor planet designation: 255 Oppavia) is a sizeable Main belt asteroid. It classified as a dark P-type asteroid.
It was discovered by Johann Palisa on 31 March 1886 in Vienna and was named after Opava, a town in the Czech Republic, then part of Austria-Hungary, where Palisa was born.
Oppavia was long thought to be a member of the now defunct Ceres asteroid family, but was found to be an unrelated interloper on the basis of its non-matching spectral type.
