PSR J0538+2817 is a pulsar situated in the constellation of Taurus. Discovered in 1996, it stirred interest from the fact that it is physically linked to the supernova remnant SNR G180.8–02.2.{{cite journal |last1=Anderson |first1=S. B. |last2=Cadwell |first2=B.

The characteristic age of PSR J0538+2817 gives an older estimate: 618,000 years. However, observation of the pulsar's proper motion gives a much younger result: 30,000 ± 4,000 years, meaning that the pulsar must have begun rotating at a relatively slow pace, at 139 milliseconds.
