Charon 630 1.47e21 1.37 .32 15.5 S (z) Key: Radius Equatorial radius in km. Mass in kilograms including atmospheres but not satellites. Dens Density in g/cm3. Abo Object's geometric albedo. Vo Object's magnitude in visible light at opposition. Rotate Sidereal period of equatorial rotation in days (negative=retrograde; S=synchronous). Dimensions Radii for non-spherical bodies. Notes: (y) Iapetus' magnitude varies from 10.2 to 11.9 (z) the masses, radii and densities of Pluto and Charon are still somewhat uncertain ( ) Some of the data above is given to more decimal places than it should be.
