(168) Sibylla is an asteroid which - like Cybele - orbits on the outer edge of the main belt in the so-called Hecuba gap.
The low albedo indicates that it contains a high proportion of carbonates .
The asteroid was discovered by James Craig Watson in Ann Arbor on September 28, 1876 and named after Sibylle , a seer from Greek mythology .
