1422 Strömgrenia

1422 Strömgrenia, provisional designation 1936 QF, is a stony asteroid from the inner regions of the asteroid belt, about 6 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 23 August 1936.〔
The asteroid is a member of the Flora family, a large group of stony S-type asteroids in the inner main-belt. It orbits the Sun at a distance of 1.9–2.6 AU once every 3 years and 4 months (1,231 days). Its orbit shows an eccentricity of 0.17 and is tilted by 3 degrees to the plane of the ecliptic. It has a rotation period of hours〔 and an assumed geometric albedo of 0.24, which is typical value for a silicaceous asteroid.〔
The minor planet was named in honour of Swedish-Danish astronomer Svante Elis Strömgren (1870–1947), professor of astronomy and director of the Copenhagen University Observatory.〔
