Slowest rotating neutron star detected: NASA
NASA has confirmed that 1E 1613, formed from a supernova explosion 9,000 light-years away, is the slowest rotating neutron star ever detected. It rotates once every 24,000 seconds, much slower than the second slowest neutron star's 10-second period. It is hypothesised that the supernova's debris had fallen back onto magnetic field lines around the star, causing it to slow down.
