1695 Walbeck, provisional designation 1941 UO, is an eccentric, carbonaceous asteroid from the outer region of the asteroid belt, about 19 kilometers in diameter. It was discovered by Finnish female astronomer Liisi Oterma at Turku Observatory on 15 October 1941.〔 The Cg-type asteroid orbits the Sun at a distance of 2.0–3.6 AU once every 4 years and 8 months (1,695 days). Its orbit shows a relatively high eccentricity of 0.29 and is significantly tilted by 17 degrees towards the plane of the ecliptic. It has a rotation period of 5.2 hours〔〔 and an albedo in the range of 0.03–0.06, according to the surveys carried out by IRAS, Akari, WISE and NEOWISE.〔〔〔〔 The minor planet was named in memory of Finnish scientist Henrik Johan Walbeck (1793–1822), astronomer and geodesist at the old Academia Aboensis who used the method of least squares to derive a good value for the Earth's flattening.〔 == References ==
