The sun rotates the fastest at the equator, whereas the rotation rate slows down at higher latitudes and is the slowest at the polar regions. But a nearby sun-like star—V889 Herculis, some 115 light years away in the constellation of Hercules—rotates the fastest at a latitude of about 40 degrees, while both the equator and polar regions rotate more slowly. This finding has been published in Astronomy & Astrophysics.
