PSR J1748−2446ad is the fastest-spinning pulsar known, at 716 Hz (times per second), [2] or 42,960 revolutions per minute.This pulsar was discovered by Jason W. T. Hessels of McGill University on November 10, 2004, and confirmed on January 8, 2005.
Spinning roughly 641 times per second, it remains the second fastest-spinning millisecond pulsar of the approximately 200 that have been discovered. [7] Pulsar PSR J1748-2446ad , discovered in 2004, is the fastest-spinning pulsar known, as of 2023, spinning 716 times per second.
This is a list of fast rotators—"minor planets" (which includes asteroids) that have an exceptionally short rotation period, i.e. high rotation rate or spin rate. In some cases the rotation period is not constant because the object tumbles (see List of tumblers).

Could it be used to detect the elusive vacuum friction?
PSR J0952–0607 is a massive millisecond pulsar in a binary system, located between 3,200–5,700 light-years (970–1,740 pc) from Earth in the constellation Sextans. [6] It holds the record for being the most massive neutron star known as of 2022, with a mass 2.35 ± 0.17 times that of the Sun—potentially close to the Tolman–Oppenheimer–Volkoff mass upper limit for neutron stars.
