14659 Gregoriana           Discovered 1999 Jan. 15 by M. Tombelli and G. Forti at Montelupo.
The Pontifical Gregorian University dates its origin to the founding of the Roman College in 1551. The name was suggested by Vatican astronomer G. Consolmagno on the occasion of the 64th meeting of Meteoritical Society in Rome in Sept. 2001.
