488 Kreusa is a C-type asteroid orbiting the Sun in the asteroid belt, with the type indicating a surface with a low albedo and high carbonaceous content. The spectra of the asteroid displays evidence of aqueous alteration.
In 2002, Kreusa was detected by radar from the Arecibo Observatory at a distance of 1.67 AU. The resulting data yielded an effective diameter of 150±21 km.
