SP-345 Evolution of the Solar
System
FIGURE 24.3.1.- Total mass of
secondary body systems as a function of central body mass. Both
Triton and the Moon have much larger masses than expected of normal
satellites. Two possible mass estimates for a normal Earth satellite
system are shown, one based on an extrapolation from the systems of
Jupiter, Saturn, and Uranus, and the other, an interpolation also
including the Martian satellite system. (From Alfvén and
Arrhenius, 1972a.)
