1844 Susilva, provisional designation 1972 UB, is a stony asteroid from the outer region of the asteroid belt, about 22 kilometers in diameter. It was discovered by astronomer Paul Wild at Zimmerwald Observatory near Bern, Switzerland on 30 October 1972.〔 The asteroid is a member or the Eos family. It orbits the Sun at a distance of 2.9–3.2 AU once every 5.23 years (1,911 days). Its low-eccentric orbit is tilted by 12 degrees to the plane of the ecliptic. The S-type asteroid has an albedo of about 0.14, with observational results of and from the WISE/NEOWISE surveys.〔〔 ''Susilva''s rotation period has not yet been measured. The discoverer named a pair of asteroids after two of his former schoolmates, Susi and Helen, both from the small village of Wald, Zürich in Switzerland. This one was dedicated to Susi, while the subsequently numbered asteroid 1845 Helewalda was given to Helen.〔 == References ==
