1019 Strackea, provisional designation 1924 QN, is a stony asteroid of the inner asteroid belt, about 8 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany, on 3 March 1924.[14]

The S-type asteroid is a member of the Hungaria family,[4] which form the innermost dense concentration of asteroids in the Solar System. It orbits the Sun at a distance of 1.8–2.0 AU once every 2 years and 8 months (965 days). Its orbit shows an eccentricity of 0.07 and is tilted by 27 degrees to the plane of the ecliptic.[1]

Several light-curve analysis rendered a well-define, concurring rotation period of 4.05 hours (also see infobox).[12][13] According to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and the U.S. Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid's surface has an albedo in the range of 0.21 to 0.31.[5][6][7]

The minor planet was named after German astronomer Gustav Stracke (1887–1943), who was in charge of the minor planet department at the Berlin Astronomisches Rechen-Institut, despite his wish that he not be honoured in this fashion.[2] Previously, the discoverer had circumvented Stracke's wish by accordingly naming a consecutively numbered sequence of asteroids, so that their first letters form the name "G. Stracke". These minor planets were:[15]
