409 Aspasia is a large main-belt asteroid that was discovered by French astronomer Auguste Charlois on December 9, 1895 from Nice. It is classified as a CX-type asteroid.[4]
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] This is consistent with previous results.[4]
