PSR B0329+54 is a pulsar approximately 3,460 light-years away in the constellation of Camelopardalis. It completes one rotation every 0.71452[3] seconds and is approximately 5 million years old.[4]
In 1979, two extrasolar planets were announced to be orbiting the pulsar (being classified as pulsar planets). Later observations however ruled out this idea.[5][4][6]
