(z) Key: Radius Equatorial radius in km (highly uncertain for the small outer solar system moons) 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 its satellites are still somewhat uncertain ( ) Some of the data above is given to more decimal places than it should be. Much more accurate and detailed data is available from JPL's Horizons telnet interface and their web site.
