712 Boliviana is a C-type asteroid from the asteroid belt, with the type indicating the surface has a low albedo with high carbonaceous content. The spectra of the asteroid displays evidence of aqueous alteration.[2] It is named after Simón Bolívar.
Boliviana was observed by Arecibo radar 2005 Oct 29-Nov 1.[3][4]
