 PHYSICAL DATA:
  Mass Pluto (10^22 kg) =   1.314+-0.018  Density Pluto:
  GM (planet) km^3/s^2  =  870               (R = 1137+-8 km)   = 2.06 g/cm^3
  Mass ratio (Mc/Mp)    = 0.12            Radius of Pluto, Rp   = 1151 km
  Surface gravity       = 65.5 cm/s^2     Geometric albedo      = 0.3
  Orbit period          = 248.0208 yr     Orbit velocity        = 4.749 km/s
  Escape velocity (km/s)= 1.3
