The Moon is Earth’s natural satellite and the brightest large object in Earth’s night sky.
3,475 kmMean diameterThe mean diameter of Moon is about 3.7 times the diameter of Ceres.
Rounded mean-radius model of Ceres. The derived area and volume describe a sphere; surface terrain and flattening are omitted.
