Betelgeuse, the red supergiant star in the constellation Orion, does indeed rotate, but very slowly. The rotation period of Betelgeuse is approximately 420.52 days or 1.15 Earth years.

In comparison to our Sun, which completes a full rotation in about 27 days, Betelgeuse's rotation rate is extremely slow. This slow rotation is perhaps a consequence of its vastly larger size as it is an incredibly large star with an average radius that is nearly 1230 times that of the Sun.

Because of its tremendous dimensions, maintaining stability against the force of rotation becomes more challenging when expanding, hence why it rotates much slower than smaller stars like the Sun.
