66458 Romaplanetario           Discovered 1999 Aug. 22 by G. Masi at Ceccano.
Without a planetarium for more than 22 years, the Everlasting City now has a modern one, opened in 2004. Hosted at the Museo della Civiltà Romana, it has a 14-meter dome. The discoverer contributes with the staff to introduce visitors to the wonders of the universe.
