S tars, all of which originally coalesced from orbiting in-spiraling gases, have some amount of angular rotation, but some stars rotate much faster than others. On the low end of rotational speed, consider our own Sun. Because it is a sphere of hot plasma rather than a solid body, its various regions can rotate at different speeds. Its equatorial region makes one complete rotation every 25.7 days, while the regions near the solar poles rotate more slowly, only about one rotation every 33 days. The spin axis of the Sun is not quite perpendicular to the plane of the ecliptic
