How Differential Rotation Works
The above diagram will help to illustrate differential
rotation. Stars or gas clouds that were lined up at one
time (points 1) are spread out by the time they have
gone 1/4 of the way (points 2) or about 3/4 of the way
(points 3) around the galaxy. The small diagrams
show the net velocity that stars or gas clouds at
different distances from the GC would have with
respect to our Sun. Objects within the Sun's orbit
around the GC are orbiting faster than does the Sun
and objects farther out than the Sun's orbit are
orbiting more slowly than does the Sun. Our Sun
complete one revolution about the GC in some 200
million years. The Sun was last on this side of the
milky way center (with respect to the universe of
external galaxies) at about the time that small
dinosaurs were beginning to develop on the Earth's
surface. It has moved through an angle of about 120°
of its orbit since the last great dinosaurs vanished.
