Discovered on October 16, 1977 by Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld on photographic plates taken by Tom Gehrels with the Samuel Oschin telescope at the Palomar Observatory, it was given the provisional designation "2078 T-3". It was later renamed "Donizetti" after Italian composer Gaetano Donizetti. [MPC 34356 "Minor Planet Center"]
