It was discovered on 3 March 1924, by astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany.[33] It is named for German astronomer Gustav Stracke.[2] Classification and orbitStrackea is a member of the Hungaria group, a dynamical group forming the innermost dense concentration of asteroids in the Solar System.[5] It is, however, a non-family asteroid of the background population, and not a member of the (collisional) Hungaria family.[6] 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.The body's observation arc begins with its official discovery observation at Heidelberg in 1924.[33] Physical characteristicsIn the Tholen classification, Strackea is a common, stony S-type asteroid.[4] LightcurveThe 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 ({{small|U=2}}).[14] 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,{{efn|name=Lightcurve-plot}} Richard Schmidt, as well as by the group of astronomers Pierre Antonini, Raoul Behrend, Roberto Crippa and Federico Manzini ({{small|U=3/3-/3-/3/3}}).[13][14][15][16][18] Diameter and albedoAccording 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.[8][9][10][11] 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.[4] NamingThis 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 {{LoMP|1227|number range from 1227 to 1234}}, were:[53]
