3325 TARDIS (prov. designation: 1984 JZ) is a dark Alauda asteroid from the outer region of the asteroid belt, approximately 29 kilometers (18 miles) in diameter. It was discovered on 3 May 1984, by American astronomer Brian Skiff at Lowell's Anderson Mesa Station, Arizona, in the United States.[6] The asteroid was named TARDIS, after the fictional time machine and spacecraft from the science fiction television series Doctor Who.[2]
