1120 Cannonia is a main belt asteroid orbiting the Sun. It was discovered by Pelageya Fedorovna Shajn on September 11, 1928 at Simeis. Its provisional designation was 1928 RV. It was independently discovered by Grigory Nikolaevich Neujmin at Simeis two days later, and ten days later by Eugène Joseph Delporte at Uccle. It was named for Annie Jump Cannon, who classified the spectral types of about 225,000 stars for the Henry Draper Catalog.[2] The asteroid completes one rotation approximately once every 4 hours and makes one revolution around the Sun about once every 3 years.[1]
