The mean diameter of the Moon is about 1.46 times the mean diameter of Pluto. Selected basis: approximate values.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions.
2,377 km - Mean diameter; approximate.
Pluto is a dwarf planet in the Kuiper Belt, composed of rock and ice and orbiting the Sun.
Mean-radius spherical model for Pluto; actual shape is not perfectly spherical.
NASA JPL — planetary physical parameters3,475 km - Mean diameter; approximate.
The Moon is Earth’s natural satellite and the brightest large object in Earth’s night sky.
Rounded mean-radius model of Moon. The derived area and volume describe a sphere; surface terrain and flattening are omitted.
