[12] In the Tholen classification, Devota is an X-type asteroid,[1][3] while the Wide-field Infrared Survey Explorer (WISE) characterized it as a primitive P-type.

[6] Other spectroscopic and photometric surveys as well as the Bus–DeMeo taxonomy classified the asteroid as a D-type due to its low albedo value and its featureless and reddish spectrum.

[10][11]: 22 In August 2009, a rotational lightcurve of Devota was obtained from photometric observations by French amateur astronomer Pierre Antonini.

[3] According to the surveys carried out by the Japanese Akari satellite and the NEOWISE mission of NASA's WISE telescope, Devota measures between 53.697 and 56.06 kilometers in diameter and its surface has an albedo between 0.043 and 0.046.

[5][6][7][8] The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is, an albedo of 0.0407 and a diameter of 57.11 kilometers based on an absolute magnitude of 10.31.
