969 Leocadia (prov. designation: A921 VC or 1921 KZ) is a very dark background asteroid from the inner regions of the asteroid belt, approximately 19 kilometers (12 miles) in diameter. It was discovered on 5 November 1921, by Russian astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula.[1] The uncommon F-type asteroid (FX) has a rotation period of 6.9 hours and is likely regular in shape.[10] Any reference of the asteroid's name to a person is unknown.[3]
