The Sun rotates faster at its Equator than its Poles
In the early 17th century, Galileo used sunspots to determine that the Sun rotates in about 27 days.  We now know that the  Sun is not a solid body.  Its equatorial rotation period rate is about 25 days, while the polar period is about 35 days.
Color code: Red is faster, blue is slower.
Helioseismology tell us that
this “differential rotation” extends far below the surface.
