1019 Strackea, provisional designation 1924 QN, is a stony Hungaria asteroid of the inner asteroid belt, approximately 8 kilometers in diameter. It was discovered on 3 March 1924, by astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany. [16] It is named for German astronomer Gustav Stracke. [2]
Strackea is a member of the Hungaria group, a dynamical group forming the innermost dense concentration of asteroids in the Solar System. [4] It is, however, a non-family asteroid of the background population, and not a member of the (collisional) Hungaria family. [5] It orbits the Sun at a distance of 1.8–2.0 AU once every 2 years and 8 months (965 days). Its orbit has an eccentricity of 0.07 and an inclination of 27° with respect to the ecliptic. [1] The body's observation arc begins with its official discovery observation at Heidelberg in 1924. [16]
In the Tholen classification, Strackea is a common, stony S-type asteroid. [1] [3]
The first valid rotational lightcurve of Strackea with a period of 4.05 hours and a brightness variation of 0.17 magnitude was obtained by French amateur astronomer Laurent Bernasconi in February 2006 ( U=2 ). [12] Since then, several well-defined lightcurves with a period between 4.044 and 4.052 hours and an amplitude of 0.15 to 0.25 magnitude were obtained by astronomers Brian Warner, [lower-alpha 1] Richard Schmidt, as well as by the group of astronomers Pierre Antonini, Raoul Behrend, Roberto Crippa and Federico Manzini ( U=3/3-/3-/3/3 ). [11] [12] [13] [14] [15]
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Strackea measures between 7.169 and 8.79 kilometers in diameter and its surface has an albedo between 0.206 and 0.39. [6] [7] [8] [9] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.2236 and a diameter of 8.37 kilometers with an absolute magnitude of 12.63. [3]
This minor planet was named after German astronomer Gustav Stracke (1887–1943), who was in charge of the minor planet department at the Berlin-based Astronomical Calculation Institute, despite his wish that he not be honored 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, in the number range from 1227 to 1234, were: [17]
Naming citation was first published by Paul Herget in The Names of the Minor Planets in 1955 ( H 97 ). [2]
