83 Beatrix (/ˈbeɪ.ətrɪks/ BAY-ə-triks or /ˈbiːətrɪks/ BEE-ə-triks) is a quite large asteroid orbiting in the inner part of the main asteroid belt. It was discovered by Annibale de Gasparis on April 26, 1865. It was his last asteroid discovery. A diameter of at least 68 km was determined from the Beatrician stellar occultation observed on June 15, 1983. It is named for Beatrice Portinari, beloved of Dante Alighieri and immortalized by him in La Vita Nuova and The Divine Comedy.
