How Fast Is Pulsar (equator)?

The fastest known pulsar's equator spins at 70% the speed of light — 716 rotations per second. That's a 20-km-wide neutron star spinning hundreds of times per second, with a magnetic field strong enough to disrupt molecules at thousands of kilometres' distance.

A pulsar 20 km wide can spin 716 times per second at its equator — 70% the speed of light.
