PSR B0329+54

PSR B0329+54 is a pulsar approximately 5,300 light-years away in the constellation of Camelopardalis. It completes one rotation every 0.7145 seconds and is approximately 5 million years old.
The emissions of this pulsar and the Vela Pulsar were converted into audible sound by the French composer Gérard Grisey, and used as such in the piece Le noir de l'étoile.

Planetary system

In 1979 and 1994, two exoplanets were reported to be orbiting the pulsar. Later observations did not support this conclusion. More recently, a 2017 analysis indicated that a different long-period pulsar planet remains a possibility, but this was subsequently challenged as well., the existence of any planet around this pulsar remains in doubt.
