400 Ducrosa is a typical main belt asteroid. It was discovered by Auguste Charlois on 15 March 1895 in Nice, and named for It J. Ducros a mechanic at the Nice Observatory.[1] This minor planet is orbiting the Sun at a distance of Script error: No such module "val". with a period of Template:Cvt and an orbital eccentricity of 0.117. The orbital plane is inclined at an angle of 10.5° to the plane of the ecliptic.[2]

This asteroid has a B-type taxonomy, indicating it has a relatively bright geometric albedo for a carbonaceous asteroid.[3] It has an estimated diameter of Script error: No such module "val"..[2] Photometric measurements of the asteroid made in 2005 at the Palmer Divide Observatory showed a light curve with a rotation period of Script error: No such module "val". and a brightness variation of 0.62±0.02 in magnitude.[4] A 2020 study found a rotation period of Script error: No such module "val". with a variation of 0.57±0.03 magnitude.[5]
