657 Gunlöd is a C-type asteroid orbiting in the Main belt near the Eunomia family. However, it is not a family member but an un-related interloper in the region because its composition is inconsistent with membership. Its diameter is about 43 km, its albedo around 0.042[1], and its rotation period is 15.7 hours[2].
