2001 Einstein (prov. designation: 1973 EB) is a bright Hungaria asteroid from the innermost region of the asteroid belt. It was discovered by Swiss astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland, on 5 March 1973.[3] The X-type asteroid (Xe) has a rotation period of 5.5 hours and measures approximately 5 kilometers (3.1 miles) in diameter. It is named after physicist Albert Einstein (1879–1955).[2]
