409 Aspasia is a large main-belt asteroid that was discovered by French astronomer Auguste Charlois on December 9, 1895 from Nice.
Photometric observations of this asteroid at the Palmer Divide Observatory in Colorado Springs, Colorado during 2007–8 gave a light curve with a period of 9.021455 ± 0.000009 hours.[3]
