The closest known pulsar to Earth is "PSR J0108-1431". It lies in the direction of the constellation Cetus, at a distance of about 85 parsecs (or 280 light years).
The crab pulsar is a neutron star, it does not have an atmosphere as far as we know.
Mizar at 78 light years.
It's about 11.5 light years away. That means it's one of the closest stars to Earth.
