(Submitted November 24, 1997)

Where is the closest neutron star?

The Answer

The neutron star which we currently rank as "nearest to Earth" is a radio pulsar called J0108-1431. It is within 100 parsecs of the Sun. A parsec is a unit of distance in astronomy; it is equal to 3.26 light years, or 3.1 x 1018 cm.
