263 Dresda is a typical Main belt asteroid. It belongs to the Koronis family of asteroids.
It has a lightly coloured surface and likely is not composed of carbonaceous materials, but is similar in composition as another Koronis family member, 243 Ida.
It was discovered by Johann Palisa on November 3, 1886 in Vienna.
Name Dresda derives from the German city of Dresden.
