Palazzolo is an assumed
S-type asteroid.
Rotation period In 2012, a rotational
lightcurve of
Palazzolo was obtained from photometric observations at the
Palomar Transient Factory in California. Lightcurve analysis gave a
rotation period of hours with a brightness amplitude of 0.16 in
magnitude (). Follow-up observations in 2013 and 2014, gave a similar period of and hours with an amplitude of 0.16 and 0.14, respectively ().
Diameter and albedo According to the survey carried out by the
NEOWISE mission of NASA's space-based
Wide-field Infrared Survey Explorer,
Palazzolo has a diameter of 9.9 kilometers and an
albedo of 0.083, while the
Collaborative Asteroid Lightcurve Link assumes an albedo of 0.10 and calculates a diameter of 8.0 kilometers. == Naming ==
