The dispersion measure (integrated electron density along the line of sight) is the smallest for any known pulsar.

This object, PSR J0437-4715, may be the closest known pulsar, and is several times closer than any other known millisecond pulsar.

The dispersion measure, 2.65cm -3 pc, is smaller than that for any other known pulsar, implying a distance from the Sun of only about 150pc.

There have been only about one hundred gamma-ray pulsars identified out of about 1800 known pulsars.

This low magnetic field is less effective at slowing the pulsar's rotation, so millisecond pulsars live for billions of years, making them the oldest known pulsars.

The combined total of 60 known millisecond pulsars creates an all-sky array.

So I sorted the catalog of known extragalactic pulsars by distance--which corresponds.

Atypical compared with many known pulsars; but stars of the BVS type would be difficult to find as compared with pulsars.

Six known optical pulsars are listed by Shearer and Golden (2002):

"There are no known pulsars with that period," he said.
