# Pulsar rotation linear velocity

I recently came upon millisecond pulsars. I knew of pulsars, I had never guessed though that they can spin so fast.

Brief research and I find its radius is about 16km, making its rotation circumference:

$$c = 2πr ≈ 100.5km$$

Given that the pulsar rotates at 716Hz, its linear velocity at the surface should be:

$$v = 716c/s ≈ 71900km/s$$

Assuming these calculations are nearly correct, could it be that any point on the rotation circumference moves at about 24% of the speed of light? Can this be possible?

Thanks for any answers that will satisfy my curiosity.

You probably shouldn't be all that surprised. For comparison, if you drop something from a long way off onto the surface of the neutron star, it will be travelling at speeds of about $$0.5c$$ when it impacts the surface.
