1696 Nurmela, provisional designation 1939 FF, is a carbonaceous asteroid from the inner regions of the asteroid belt, about 10 kilometers in diameter. It was discovered by Finnish astronomer Yrjö Väisälä at Turku Observatory on 18 March 1939.[10] It belongs to the small Baptistina family of asteroids and is its second-largest member after the family's namesake, 298 Baptistina.
The asteroid orbits the Sun at a distance of 2.0–2.5 AU once every 3 years and 5 months (1,243 days). Its orbit shows an eccentricity of 0.10 and is tilted by 6 degrees to the plane of the ecliptic. It has an absolute magnitude of 12.9 and a rotation period of 3.159 hours.[8][9] The albedo of the C-type asteroid lies in the range of 0.06–0.13, according to the Akari, WISE/NEOWISE surveys and other observations and assumptions.[3][4][5][6]
The minor planet was named in honor of Finnish academician Tauno Kalervo Nurmela (1907–1985), some time professor of Romanic philology and later chancellor of University of Turku.[2]
