[1] In March 2011, a rotational lightcurve of Abanderada was obtained from photometric observations by French amateur astronomers Pierre Antonini.
[3] According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Abanderada measures between 29.508 and 31.74 kilometers in diameter and its surface has an albedo between 0.06 and 0.093,[5][6][7] while the Japanese Akari satellite found a diameter of 36.49 kilometers with an albedo of 0.061.
[8] The Collaborative Asteroid Lightcurve Link adopts the results obtained by the Infrared Astronomical Satellite, that is, an albedo of 0.0523 and a diameter of 39.28 kilometers based on an absolute magnitude of 10.85.
The name "Abanderada" may be translated from Spanish as "woman with a banner"—an appellation frequently used in reference to her as a crusader for social and political change.
