of approximately 7kilometers 7 km, Apollo asteroid is likely the largest known potentially hazardous object, despite its fainter absolute magnitude of 15.2, compared to other listed objects in the table below (note: calculated mean diameters in table are inferred from the object's brightness and its (assumed) albedo. They are only an approximation.).
