In the
Tholen classification,
Devota is an
X-type asteroid, while the
Wide-field Infrared Survey Explorer (WISE) characterized it as a primitive
P-type. 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.
Rotation period In August 2009, a rotational
lightcurve of
Devota was obtained from photometric observations by French amateur astronomer
Pierre Antonini. Lightcurve analysis gave a
rotation period of 17.49 hours with a brightness amplitude of 0.20
magnitude (). The observer also notes that there are several other possible period solutions ("plusieurs solutions entre 0.6 et 1 jour"). As of 2017, no secure period has been obtained.
Diameter and albedo 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. 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. == Naming ==
