1238 Predappia (1932 CA) is a main-belt asteroid discovered on February 4, 1932, by L. Volta at Pino Torinese.^[1] It was later named after Predappio, the village where Benito Mussolini was born.^[2]

Photometric observations of the asteroid during 2006 at the Palmer Divide Observatory in Colorado Springs, Colorado, were used to generate a light curve with a period of 8.94 ± 0.02 hours and a variation in brightness of 0.03 ± 0.01 magnitude.^[3]
