383 Janina is a Themistian asteroid, approximately 46 kilometers (29 miles) in diameter. [2] It is spectral B-type and is probably composed of primitive carbonaceous chondritic material. [3]
It was discovered by Auguste Charlois on 29 January 1894 in Nice. [2] [4] The reference of the name is unknown, though it is the French name of Ioannina in Greece, as well as a common German woman's name, both of which probably descend from Johannes. [4]
