Question: How fast can a pulsar spin?  — Anna

Answer: The fastest spinning pulsar has been clocked at a rate of 716 times per second.  Most pulsars, though, should possess enough self-gravity to spin as fast as 1000 to 1500 times per second before they either slowly lose energy due to the release of gravitational radiation or break apart.
