10001 Palermo is a main-belt asteroid. Discovered on October 8, 1969, it was named "Palermo" after Palermo, the capital of Sicily where Giuseppe Piazzi made the first discovery of an asteroid, 1 Ceres.[4] The naming was made in January 2001 to honour the discovery of Ceres, as that was the 200th anniversary of that discovery.[5]
The asteroid is about six kilometers in radius, although it may be irregularly shaped. It orbits the Sun every 3.67 years.
