It was discovered on 19 October 1922, by Spanish astronomer Josep Comas i Solà at the Fabra Observatory in Barcelona.

[2] Amelia is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.

[5][12] In October 2000, a rotational lightcurve of Amelia was obtained from photometric observations by American amateur astronomer Robert A. Koff at the Thornton Observatory (713) in Colorado.

[13] In 2016, a modeled lightcurves using photometric data from various sources, rendered a concurring sidereal period of 9.51856±0.00005 h and two spin axes of (80.0°, 30.0°) and (282.0°, 30.0°) in ecliptic coordinates.

[6][7][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1183 and a diameter of 50.94 kilometers based on an absolute magnitude of 9.4.
