Figure 7.7: The velocities of the planets are plotted
as a function of their distance. The rotation curve
illustrates that the orbital velocities decrease with the
square root of their distance from the Sun. Note: the
sizes of the planets are not to scale.

All planets in our Solar System follow this relation,
but stars in galaxies do not. They follow a different
relation that is specific to the details of those
systems. However, it is still derived from the laws
of gravity.
