What does this number measure?
Mean diameter calculated from the volume-equivalent radius in the NASA/JPL table. Rings and the outer atmosphere are excluded.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
Catalogue value: a source is provided, but the measurement has not been individually audited in this project.
