Aspasia ( minor planet designation: 409 Aspasia) is a large main-belt asteroid that was discovered by French astronomer Auguste Charlois on 9 December 1895 in Nice. It is classified as a CX-type asteroid. [5]
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. [4] This is consistent with previous results. [5]
