400 Ducrosa is a typical Main belt asteroid.

It was discovered by Auguste Charlois on 15 March 1895 in Nice.

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]
