A three-dimensional model of 400 Ducrosa based on its light curve

Photometric measurements of the asteroid made in 2005 at the Palmer Divide Observatory showed a light curve with a period of 6.87 ± 0.01 hours and a brightness variation of 0.62 ± 0.02 in magnitude.[2]

It is named for J. Ducros, a mechanic at the Nice Observatory.[3]
