It was discovered on 3 March 1924, by astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany.
[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,[a] 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.
