1120 Cannonia is a main belt asteroid orbiting the Sun. It was discovered by Russian astronomer Pelageya Shajn on September 11, 1928, at Simeiz Observatory in Crimea. Its provisional designation was 1928 RV. It was independently discovered by Grigory Neujmin at Simeis two days later, and ten days later by Eugène Delporte at Uccle. The asteroid completes one rotation approximately once every 3.8 hours and makes one revolution around the Sun about once every 3.3 years.[1]
It was named for American astronomer Annie Jump Cannon, who classified the spectral types of about 225,000 stars for the Henry Draper Catalog.[2]
